NOTICES OF PAPERS CONTAINED IN OTHER JOUWNALS. BYHENRY WATTS B.A. F.C.S. On a New Saline Compound of Cobalt.* By E.St. Evre. This compound is formed by the action of an alkaline nitrite on a solution of a proto-salt of cobalt. A solution of nitrite and nitrate of potash (obtained by passing a stream of nitrous gas resulting from the action of nitric acid on starch and left to cool) is passed in a fine stream by means of a pipette into a cold concentrated solution of nitrate of cobalt to which a sufficient quantity of nitric acid haa been added to render it strongly acid. Copious red fumes are then evolved the liquid becomes continually deeper in colour and at last assumes a very decided red-brown colour. At the same time there is formed a pulverulent substance having a fine yellow tint which continually increases in quantity as the liquid approaches a state of saturation and gradually falls to the bottom.As the potash-solution is always alkaline a blue sub-salt which always results from the reaction of an alkaline carbonate on a cobalt-salt is often observed to form as the potash-salt begins to predominate. In that case it is necessary to add more nitric acid so as to keep the liquid constantly acid. The same yellow precipitate is formed when the sulphate or chloride is used; but the nitrate produces it most readily and in greatest quantity. Nitric oxide continues to rise in small bubbles which rise gently from all parts of the liquid during the whole operation and its evolution is indispensable to the formation of the precipitate.The operation is stopped when the liquid has become almost colourless; the new substance is then held in suspension but gradually falls to * Ann. Ch. Phj-s. [3] XXXVIIL 177. ST. EVRE ON A NEW SALINE COMPOUND OF COBALL'. the bottom. While the deposition is going on the liquid must be kept coiistantly acid ;otherwise the precipitate will retain a greenish tinge arising from the mixture of the blue sub-salt above mentioned with the yellow compound. As soon as the liquid has become clear it is decanted and the precipitate several times washed with cold distilled water till the wash-water becomes neutral to test-paper ; after which it is collected on a filter and dried at a temperature between 115' and 120' C.The new precipitate is nearly insoluble even in water acidulated with nitric acid; when the solutions used are pure and sufficiently concentrated an almost complete decoloration of the liquid takes place. The author at first thought that the action of nitrite of potash on a cobalt-salt might furnish the means of effecting a complete separation of nickel and cobalt inasmuch as nickel under the same circumstances does not yield an analogous compound. This expectation however was not fulfilled for the precipitate after all is not absolutely insoluble. The liquid from which the yellow precipitate has separated contains a small quantity of nitrate of cobalt which has either remained unacted upon or has been produced by partial decomposition of the new salt and a considerable quantity of nitre which soon crystallizes if the solution be sufficiently concentrated.The action of nitrite of potash on nitrate of cobalt gives rise therefore to the production :-1. of nitric oxide which escapes and forms red fumes in the air; 2. of nitrate of potash; 3. of the yellow precipitate. The same yellow precipitate may also be obtained by suspending the blue subnitrate-obtained by precipitating the neutral nitrate with potash-in an excess of the alkaline nitrite whereupon part of the precipitate is redissolved ;the liquid must then be gently agitated while a thin stream of nitric or hydrochloric acid is suffered to fall into it. This process has the advantage of yielding a larger product in proportion to the quantity of material used; but on the other hand the colour of the precipitate is spoiled by a tinge of green which it retains even after repeated washings with acidulated water.Lastly this yellow compound may be formed synthetically by bringing protoxide of cobalt in contact with potash and hyponitric acid or which comes to the same thing a mixture of nitric oxide and oxygen. A rather strong solution of nitrate of cobalt-which need not however be pure-is mixed with a sufficient quantity of potash to determine the precipitation of the blue sub-salt and then by agitation that of the rose-coloured hydrated protoxide the magma thus produced is poured into a wide and tall foot-glass care being taken to moisten the sides with the liquid and a stream of nitric oxide passed into it.In a few minutes-as soon indeed as a sufficient quantity of hyponitric acid has been formed-the yellow colour makes its appearancc on the ST. EVIlE ON sides of the vessel and by continuing the passage of the gas a complete transformation is obtained. The action is sufficiently prompt and decided to be exhibited as a lecture experiment. This substance possesses the following properties. Its colour is a brilliant yellow. When examined by the microscope it is found to consist of quadrilateral prisms terminated with triangular facets. It is heavier than water neutral to litmus very sparingly soluble in water perfectly insoluble in alcohol and ether. Sulphide of carbon dissolves traces of it. Water at 100' decomposes it after some titne with separation of nitric oxide which by contact of air is finally converted into nitric acid part of which is carried off with the vapour of water and part enters into the composition of the new product; the liquid at the same time acquires a rose colour.The yellow compound suspended in water resists the action of a stream of chlorine gas even if continued for a day. To effect the decomposition and obtain the characteristic rose colour of the ordinary salts of cobalt the liquid must be heated; red fumes are then evolved and there remains a double chloride of cobalt and potassium. The yellow compound under the same circumstances resists equally well the action of a stream of sulphuretted hydrogen the formation of sulphide of cobalt not beginning till after a considerable time ; but sulphide of ammonium blackens it almost instantly.Acids decompose it with evolution of red fumes of hyponitrie acid. An aqueous solution of ammonia does not act upon it till after a considerable time and even then but partially. Heated by a spirit-lamp in a stream of hydrogen it gives off vapour of water mixed with abundance of ammoniacal vapours; the same result is however obtained under similar circumstances with ordinary nitrate of cobalt. This reaction would indicate the degree of oxidation of the cobalt if the nitrogen were completely removed by it; but this is not the case. The residue which has a metallic appearancc still gives off red vapours when treated with sulphuric acid ;moreover the potash which enters into the composition of the salt melts and forms a kind of varnish over it which prevents the further action of the gas.An aqueous solution of potash decomposes the salt throwing down the hydrated sesquioxide of cobalt. This hydrate gradually loses its water at loo' retaining only a single equivalent which it does not give up till heated above 155'. It is moreover slightly soluble in warm water. The compound heated with sodium in a bent tube is decomposed with violence leaving a metallic sponge of firrelydivided cobalt which 1 eadily acquires metallic lustre by friction. A NEW SALINE COMPOUSD OF COBALT. The salt heated with solid potash or soda in a closed tube does not give off ammoniacal vapours.When calcined in contact with the air in a tube closed at the bottom it changes colour and assumes an orange-red tint. At the same time it fuses and gives off small gas-bubbles from the whole of its mass; a very small quantity of water likewise separates from it and red vapours of hyponitric acid are evolved together with white vapours of nitric acid. The liquid which distils off has a slight yellow tint and is so strongly acid that it quickly corrodes the corks. The residue consists of sesquioxide of cobalt and nitrite of potash. If the decomposition be stopped at the moment when the water and the acid-vapours cease to escape the substance is found to have lost 28-95 per cent of its weight-a loss which corresponds to 2 equivs. of nitrogen 9 equivs.of oxygen and 1 equiv. of water. But the products vary with the manner in which the heat is applied and the operation conducted. When the decomposition takes place in an atmosphere of dry nitrogen or carbonic acid similar results are obtained excepting that nitric oxide is found among the products and the red vapours disappear almost as soon as they are formed being replaced by those of nitric acid. The residue in this case also consists of nitrite of potash and sesquioxide of cobalt. Lastly when the substance is decomposed by the heat of a charcoal fire and in a current of carbonic acid a gaseous mixture is obtained which after the carbonic acid has been absorbed by potash and the nitric oxide by protosulphate of iron yields pure nitrogen.The cobalt was estimated by boiling the salt with acetate of soda mixed with a little acetic acid to neutralize the alkalinity; adding to the dark brown liquid thus obtained an aqueous solution of sul-phuretted hydrogen ; dissolving the sulphide of cobalt in very dilute nitric acid (a stronger acid would oxidize the sulphur) and at a temperature not exceeding 50' C. ;calcining the resulting nitrate to convert it into sesquioxide and reducing this oxide to the metallic state in a current of hydrogen gas. The sesqgioxide must be carefully examined for sulphur and that substance estimated if present and its weight deducted; and the bulb containing the reduced metal must be strongly heated by the blow-pipe; otherwise the metal which is pyrophoric will be reoxidized as soon as it comes in contact with the air.The potash was precipitated by chloride of platinum after the separation of the cobalt If the cobalt be not first separated a portion of it is always carried down with the chloride of platinum and potassium. Hydrofluosilicic acid cannot be used to precipitate the potash because it forms a soluble double hydrofluosilicate of potash and cobalt.-The nitrogen is easily estimated by the usual method. Sl'.

The nitrogen appears to be in the form of nitric and nitrous acid and we might at first suppose that the yellow salt is a compound of nitrate of potash with nitrite of cobalt or vice versa". But if that were the case the salt ought to be formed by the first process (p. 83),without evolution of gas or formation of nitre. Now nitrite of potash is always alkaline and when treated with acids gives off nitric oxide; and this nitric oxide decomposes the nitric acid present converting it into hyponitric acid NO +2 NO =3 NO,.Hence the action may be represented by the following equation CbO NO +2NO +4 (KO NO,) =3 (KO NO,) +2 NO, +CbO KO 2 NO,. 1.- Yellow salt. The formula must however be doubled fir$ on account of the presence of water in the salt (1 equiv. of water to 2 equivs. of salt) and secondly because the salt when decomposed either by potash in solution or by calcination in contact with the air yields sesquioxide of cobalt. The formula is therefore as follows 2 (N 0, CbO KO) HO. This forniula requires Calculation.

The exact mode of grouping of the elements cannot at present be determined. The salt calcined in contact with the air gives off all its water and is converted into anhydrous sesquioxide of cobalt Cb 0,. This compound from the beauty of its colour its permanence and its capability of resisting the ordinary agents of sulphuration and oxidation appears to be well adapted for painting. Experiments have been made with it both as an oil and as a water-colour alone and mixed with white-lead mineral blue and vermilion and all have yielded satisfactory results. The mixture with vermilion was the only one which underwent any change of colour assuming a greyish tint ; but this is always the case with vermillion when exposed to light.The new pigment may be designated by the name of Cobalt-yellow. On the Decomposition of the Cyanic Ethers.* By A. WUl'tZ. When cyanic ether is placed in contact with water carbonic acid is disengaged and diethylurea is formed. On the other hand this ether acts with few exceptions on all the compounds derived from the type water and the products of the reaction are to a certain extent similar to those just mentioned. In fact carbonic acid is often evolved and a product is also formed analogous to the amides. It is true taliat diethylurea is not an amide but it bears a very close relation to that class of bodies; for it is isomeric with diethylo-carbamide and nothing prevents us from supposing that at the moment of its formation it is produced by the molecular transposition of carbamide.The following formuh exhibit the existing relations between these products c,o2 N H = Carbamide. Urea. If then the action of water on cyanic ether gives rise to urea whereas ainides are formed by the action of the derivatives of water on cyanic ether the relations which exist between these products and * Compt. Rend.

This will be further seen from the following experiments which moreover point out a new mode of formation of the amides.When cyaDic ether is mixed with monohydrated acetic acid c4H&02 } 0, carbonic acid is evolved and Etliylacetamide is pro-duced. The reaction is expressed by the following formula c4202}0,+C6-H NO,=2C 02+N -Cyanic ether. Acetic acid. Ethylacetamide. This compound was first obtained by M. Wurtz two years ago by the action of ethylamine on acetic ether. Cyanic ether acts upon anhydrous acetic acid. When these liquids in about equal volumes are enclosed in a tube of green glass the tube hermetically sealed and then immersed in an oil-bath heated to 180° the reaction takes place the products being carbonic C4H5 acid and ethylo-diacetaniide N2 C4H,02 as shown by the fol-lowing equation (,4H302 ,0,+C6€I,N0,= ’-/ -Anhydrous Cyanic ether.u acetic acid. Ethylo-diacetamide. Ethylacetamide and ethylo-diacetamide are evidently analogous to the compoiind amides” which Gerhardt has obtained by a totally different process. It will readily be understood that the process just described may like Gerhardt’s be applied to the formation of a large number of new amides. Alcohol itself may be referred to the type of water. Cyanic ether decomposes it likc the preceding compounds only it does not evolve carbonic acid in this reaction; but the elements of the two bodies combine and group themselves in such a manner as to form ethylurethane. The reaction is as follows -Alcohol. Cyanic ether. Ethylurethane.JOY ON SELENIDE OF ETHYL. Ethylurethane may be regarded as ethylocarbamic ether and is therefore related to the amides like carbamic acid itself. Common ether C4H5}0 does not act at all or acts with great C*% difficulty on cyanic ether. The autbor enclosed these two highly volatile liquids in very strong tubes and heated them to very high temperatures at enormous pressures. On opening theni after cooling no evolution of gas was observed; and on distilling the contents the distillate was found to consist of unaltered ether and cyanate of ethyl. At the end of the distillation however at a temperature of 200° a peculiar volatile liquid passed over but in quantity too small for analysis. This liquid might be diethylurethane ; but from the qualitative examination which the author made of it this view of its nature appears to be doubtful.On Selenide of Ethyl or selenethyl. Ily C. A. JOY*+ .SeIenide of ethyl was discovered in 1836 by Lijwig who obtained it by distilling dry selenide of potassium with oxalic ether. The following experiments which were undertaken with the view of ascertaining whether this body acts as an organic radical analogous to telluride of ethyl were made with a product obtained by distilling a solution of selenide of potassium with sulphoviriate of potash. To prepare the monoselenide of potassium hydrate of potash was dissolved in four parts of water the solution divided into two equal parts one portion completely saturated with seleniuretted hydrogen gas and then the other half added.The seleniuretted hydrogen was evolved by the action of hydrochloric acid on selenide of iron (obtained by heating a mixture of equal parts of iron and selenium in a glass retort). As the gas decomposes in contaet with the air it is necessary to pass a stream of hydrogen through the apparatus before the action begins; the hydrogen-apparatus may also be left in connection while the evolution of the seleniuretted hydrogen is going on so that at the end of the process hydrogen may be again passed through the apparatns to drive the last portionv of seleniuretted hydrogen into the potash-ley which should Iikewise be surrounded by an atmosphere of hydrogen. The solution of selenide of potassium thus obtained was mixed * Ann.Ch. Pharm. LXXXVl 35. JOY ON SELENIDE OF ErmL. with a concentrated solution of sulphovinate of potash in a flask provided with a condensing tube and rapidly distilled the oper a t' ion being continued as long as drops of selenide of ethyl passed over with the water. For one part of selenium there were used two parts of hydrate of potash and four pints of sulphovinate. Selenethyl is a clear pale yellow liquid having a most insuf- ferable odour. It is much heavier than water and does not mix with it. When set on fire it burns with emission of red vapours of selenium. Nitrate of XeZenethyZ.-Formed by dissolving selenet hyl in hot moderately strong nitric acid the action being attended with evolu- tion of nitric oxide gas. It was not obtained in the dry state but only in the form of a concentrated solution which began to decom- pose when further evaporated.That it really is the nitrate of sele- nethyl appears from the following experiments :-Chloride of XeZenethyZ. C,H,SeCl.-The solution of selenide of ethyl in nitric acid behaves with hydrochloric acid just like that of tellurethyl; on the addition of the acid it becomes milk-white and immediately afterwards drops of an oily body separate out. This substance is the chloride of selenethyl. It is a transparent light yellow liquid which sinks in water; when quite pure it appears to be inodorous. It is somewhat soluble in water and still more in hydrochloric acid which circumstance renders some care necessary in preparing it.It was found by analysis to contain 33.87per cent. of chlorine The preceding formula requires 34.9 per cent. The greater part of the chloride of selenethyl obtained as above having been left for a considerable time in contact with the liquid containing hydrochloric and nitric acid in which it had been pro- duced a number of transparent and colourless crystals were observed to form at the separating surface of the two liquids. These crystals were very well defined and considering the small quantity of consi- derable magnitude. The author was not able to determine the exact nature of this body; but by its mode of decomposition when heated and its ultimate analysis it appeared to be an organic compound containing chlorine and selenium. It did not exhibit the characters .of a hydrate of the chloride of selenethyl by solution in water or by any other means.It dissolves readily in water and in alcohols and separates out unchanged on evaporating the liquids. Its aqueous solu- tion is not clouded by hydrochloric acid ; it has an acid reaction. The body appears to be an acid for it forms with ammonia a highly crystalline mass from which the ammonia is eliminated by potash. Hydrochloric acid did not precipitate chloride of selenethyl from it a proof that no oxychloride of selenethyl had been formed by the action of the ammonia. On the other hand sulphurous acid added to it separated selenethyl. Analysis showed that it contains 13%8 BERTAGNINI ON AMARlNE PURFURINE AND ANISINE. per cent.carbon 4.298 hydrogen and 20.05 chlorine; whence we may infer that it contains 4 eq. chlorine to 4eq. carbon. OxychZoride of Selenethyl. C,H,SeO +C,H,SeCl.-Chloride of selenethyl dissolves readily in ammonia producing chloride of am-monium and oxychloride of selenethyl. After evaporating the solu- tion the oxychloride may be extracted by absolute alcohol. It crystallizes in highly lustrous colourless cubes generally grouped in stellate masses. Hydrochloric acid added to its aqueous solution throws down the oily chloride of selenethyl; and sulphurous acid throwsdown a stinking mixture of selenethyl and the chloride. These reactions indicate its composition. Bromide of Selenethyl separates in the form of a lemon-yellow oil sinking in water when a solution of the nitrate is mixed with hydrobromic acid.Iodide of SeZenethyZ. C,H,SeI.-Produced when a solution of the nitrate or even of the chloride is mixed with hydriodic acid. Black liquid with a semi-metallic lustre sinking in water; very much like bromine. It is inodorous and does not solidify at OOC. These two compounds dissolve easily in ammonia and form an oxybromide and oxyiodide of selenethyl which however have not been further examined. On the formation of Amarine Furfurine and a new Base Anishe.* By C. Bertagnini. Having found that trinitro-hy- drobenzamide may be transformed into trinitro-amarine by the mere action of heat the author was induced to express a hope? that other hydramides might also by this simple agent be converted into isomeric bases.Experiments made with this view on hydrobenzamide hrfuramide and anis* hydramide have led to satisfactory results. Pure hydrobenzamide heated for three or four hours to a tempera- ture of 120' to 130' C. yields on cooling a vitreous mass con- sisting entirely of amaxhe. On dissolving this mass in boiling alcohol and adding an excess of hydrochloric acid white crystals of hydrochlorate of amarine soon form in the liquid. By one * Ann. Ch. Pharm.

The analysis of the salt led to the formula C, H, N . H C1. Furfuramide may in a similar manner be converted into fur-furine by exposure for half an hour to a temperature of 110' to 120'.By dissolving the resulting brown mass in alcohol and adding an excess of oxalic acid a salt is obtained having all the properties of binoxalate of furfurine and yielding the base when treated in the usual manner. The facility with which furfuramiclc is converted into hrfurine affords a method of preparing this base directly from furfurol. It is only necessary to pass dry ammoniacal gas into furfurol heated to 110" to 120'; the furfurol then turns brown and in the course of half an hour or an hour is completely converted into furfixrine. Pure anishydramide heated in an oil-bath to about 120° melts into a yellowish liquid which if heated for two hours to a tempera- ture of 165' to 170" is completely converted without alteration of external appearance into a new base isomeric with anishydramide which may be called Anisine.To obtain this base in a state of purity the product must be dissolved in boiling alcohol and hydro-chloric acid added. The liquid then solidifies on cooling to a mass of interlaced crystals which when freed from the mother-liquor and decomposed by potash or ammonia yield the new base in the free state. Anisine crystallizes in transparent prisms which are scarcely soluble in water but dissolve in alcohol and sparingly in ether. The solutions of this base have a strong alkaline reaction and a bitter taste. Its formula is With acids it yields crystallized salts of definite constitution.Hydrochlorate of anisine crystallizes in white strongly lustrous needles which dissolve sparingly in water but readily in alcohol. Dried at ordinary temperatures it contains C, H, N,06. H C1+ 24 H 0; at loo' it parts with its water and is reduced to C, H, N 0 .H C1. The platinum double salt forms shining laminz of a pale orange colour. It dissolves sparingly in alcohol and is composed of C, Ha4N 0,. H C1+ Pt Cl,.
