180 DETERMINATION OF ORGANIC ACIDS [Proc. SOC. Analyt. Chem. Determination of Organic Acids The following are summaries of papers presented at the Joint Meeting of the Midlands Section with the Birmingham and Midlands Section of the Society of Chemical Industry held on September 21st 1966 and reported in the October issue of Proceedings (p. 155). Some Aspects of the Polarography of Unsaturated Aliphatic Acids BY M. L. RICHARDSON AND P. E. LUTON (John & E. Stzzvge Ltd. Liflord Chemical Wovks Kings Norton Birmingham 30) MR. RICHARDSON said that the first report in the literature dealing with the determination of fumaric and maleic acids was that made by P. Herasymenko (2. Electrochem. 1928 34 74) who had found that in an aqueous acid supporting electrolyte the two acids reduced at the same potential.L. Schwaer (Chemicke’ Listy 1932 26 485 and Collvt Czech. Chem. Commum. Engl. Ed% 1935 7 326) had described polarographic techniques for the determination of a number of unsaturated aliphatic acids including fumaric maleic aconitic mesaconic and citraconic acids. From the findings of Schwaer and many other workers it was postulated that the electro-reduction proceeded as follows- HCCOOH HCCOOH II The dependence of added before the second H~COOH I :CCOOH H HCCOOH I H+ HCCOOH -+ :CCOOH HCCOOH + 1 e- H H the reduction on the pH appeared to indicate that a proton was reduction step which then proceeded as follows- H HCCOOH I H+ HCCOOH I H~COOH H~COOH -* H H P. J. Elving et al. (Analyt. Chem. 1953 25 1082) had described a number of supporting electrolytes at various pH values for the determination of fumaric and maleic acids but maintained that an ammoniacal buffer (ammonium chloride and ammonia solution) at pH 8.3 was most suitable for the polarographic determination of these acids in admixture.A. L. Markman and E. V. Zinkova (Zh. Obshch. Khim. 1957 27 1438) had described in detail the effect of pH and of the use of non-aqueous supporting electrolytes for the determination of citraconic mesaconitic and cis and trans aconitic acids in cis - trans admixture. Mr. Richardson and his colleague confirmed the findings of Markman and Zinkova and recommen- ded the use of ethanolic hydrochloric acid as supporting electrolyte for the determination of these cis and trans aliphatic acids. Further it was found that after a simple extraction procedure it was possible to determine less than 20 p.p.m.of maleic acid in the presence of fumaric acid when using the above electrolyte. It was even possible to improve the resolution of this determination by the use of instruments which had the facility for first and second derivative function or the use of matrix algebra or both. Unsaturated organic acids with conjugated double bonds were easily reducible at the dropping-mercury cathode. In aqueous solutions of strong acids only undissociated molecules of unsaturated acids were reduced requiring 2 Faradays of electricity per mole at potentials from - 0.4 to - 1.0 volt. In neutral and alkaline medium anions of the unsaturated acids were reducible at potentials from - 1.2 to - 2.1 volts. The cis forms of the acids were reduced at the same potentials as the tram isomers in aqueous acid solutions; in neutral solutions or acid solutions containing ethanol they had different reduction potentials thus allowing their simultaneous polarographic determination.December 19661 DETERMINATION O F ORGANIC ACIDS 181 Mr. Richardson continued by saying that although attempts had been made by Schwaer A. G. Nerheim and C. R. Estee (Proc. S. Dak. Acad. Sci. 1952 31 l l l ) R. C. Rooney (in a private communication) and themselves to determine crotonic itaconic and levulinic acids polarographically these attempts had been unsuccessful. The electrode reaction mainly caused the discharge of hydrogen ions ; the characteristic polarographic curves obtained with these acids could best be explained by assuming that in the optimum pH range a catalytic hydrogen wave resulted.This study further substantiated the belief that unconjugated unsaturated acids were not reducible at the dropping-mercury electrode under polarographic conditions. The observation by R. P. Linstead and J. T. W. Mann ( J . Chem. SOC. 1931 726) that citraconic and mesaconic acids were formed on tautomerising itaconic acid by refluxing with sodium hydroxide had enabled the speaker and his colleagues to develop a polarographic procedure for determining itaconic acid as the sum of citraconic and mesaconic acids in hydrochloric acid - sodium chloride supporting electrolyte. Mass Spectrometric Identification of Fatty Acids BY T. H. SHUTTLEWORTH ( Unilevev Research Labovatovy Port Sudight Cheshive) DR. SHUTTLEWORTH said that the application of mass spectrometry to the structural problems of organic chemistry had made tremendous strides in the last decade.No other single physical technique could give the wealth of information available in the mass spectrum of a molecule. Most of the classical work on the relationship between mass-spectral breakdown and chemical structure had however been carried out at resolutions of the order of 400. Modern theories of organic chemistry had been applied with considerable success to explaining the breakdown of organic molecules under electron impact. The marked effect of functional groups on breakdown was attributed to the easy loss of an electron from a hetero atom such as oxygen or nitrogen. The subsequent localisation of the positive charge on that atom affected electron migration within the molecule and thus determined the pattern of bond cleavage.Most of the systematic studies had been carried out by Ryhage and Stenhagen in Sweden particularly in connection with fatty acids of biochemical interest. The mass spectra of fatty acids were characteristically affected by the nature and position of substitution along the chain. Hence it was generally a relatively easy matter to determine the structure of the chain. The more common substi- tuent groups to be considered were methyl hydroxy methoxy and carbonyl (0x0-acids). Cleavage was generally enhanced at carbon - carbon bonds adjacent to the position of substi- tution. A highly branched acid derived from butterfat for example had been identified as 3- 7- 11- 15- methyl hexadecanoic acid. Carbonyl groups substituted in the chain showed the expected “McLaff erty re-arrangement,” vix.cleavage of the carbon - carbon bond /3- to the carbonyl group with simultaneous re-arrangement of a hydrogen atom to the carbonyl- containing fragment. The explanation of this type of cleavage was probably the classic example of the application of organic theory to mass-spectral breakdown. The ester carbonyl group behaved in a similar way and was responsible for a characteristic re-arrangement fragment [CH,OC(OH) = CHR]+ at m/e 74 for methyl esters not substituted at the a-carbon atom and at m/e 88 for 2-methyl m/e 90 for 2-hydroxy and m/e 104 for 2-methoxy esters. The spectra of unsaturated esters were not very informative apart from giving molecular weight and degree of unsaturation. Because of the lability of the double bond its position could only be determined by selective labelling.The best method was by non-catalytic deuteration but oxidation to the corresponding 0x0-acids or to the epoxy acids might also be successful. Recently by direct insertion of the sample into the source it had become possible to obtain spectra of glycerides directly and thereby to establish not only the fatty acid com- position of the glyceride but also in many cases the relative positions of the fatty acids on the glycerol residue. This was a significant development as it presented considerable advan- tages in economy of time and material over the normal methods of glyceride analysis such as chemical and enzymatic hydrolysis followed by methylation and gas chromatography. Results could be obtained on a few micrograms of material.Another recent development This was particularly true of high resolution mass spectra. Fatty acids were best examined as their methyl esters. 182 DETERMINATION OF ORGANIC ACIDS [Proc. SOC. Analyt. Chem. that could be expected to simplify the analysis of complex fatty acid mixtures was of course the direct combination of gas chromatography and mass spectrometry. Some Aspects of the Analytical Chemistry of Soil Humic Acids and Related Synthetic Materials BY JOHN M. THOMPSON (Department of Chemistvy The University of Birmingham Edgbaston Bivminghawa 15) THE classification of soil organic matter was discussed by Mr. Thompson and a simple scheme of classification according to solubility was presented. Insoluble soil organic matter was termed “humin”; material insoluble below pH 1 but soluble above pH 1 was termed “humic acid”; and material soluble below pH 1 was termed “fulvic acid.” A scale of extraction efficiencies for various solvents used in the extraction of humic acid was presented; 0 .5 ~ sodium hydroxide 1 ; dimethylsulphoxide and dimethylformamide 0.5 ; anhydrous ethylene- diamine 1.3; 2 . 5 ~ aqueous ethylenediamine 1.8 (from unpublished data of R. S. Swift Department of Chemistry University of Birmingham). Elemental composition was as follows carbon 45 to 65 per cent. hydrogen about 5 per cent. nitrogen 2 to 6 per cent. oxygen (partially by difference) 48 to 30 per cent. of which little more than half was accounted for by functional group analysis. The molecular weight ranged from 3000 to 300,000; the carbon content increasing and the oxygen content decreasing with increasing molecular weight.The colour ranged from dark-brown to black and the chromo- phores were probably quinonoid in origin. Carboxylic acid and phenolic hydroxyl groups were responsible for the acidity and the equivalent weight ranged from 100 to 300. Alkaline hydrolysis and sodium amalgam reduction both gave up to 25 per cent. of phenolic com- pounds. Oxidation with even relatively mild reagents e.g. 6 per cent. hydrogen peroxide or alkaline potassium permanganate yielded mainly carbon dioxide water formic and acetic acids. However oxidation with dilute nitric acid gave in total 5 to 30 per cent. of picric acid benzene carboxylic acids nitrobenzoic acid nitrophenols and monocarboxylic aliphatic acids. Strong electron-spin resonance signals (about 181e spins per g) which increased on neutralisation with alkali and decreased again on re-acidification to their original level were observed.This seemed to indicate the presence of semiquinone-type free radicals. The alkali-metal salts of humic acids were soluble in water but the alkaline-earth metal salts were insoluble ; humic acids themselves were peptisable. Methods for determining the various functional groups responsible for the acidic and oxidation - reduction properties were then reviewed. The precautions necessary when carrying out such determinations were discussed. The work of Chaterjee and Bose ( J . Colloid Sci. 1952 7 414) on the determination of total acidity in the absence and presence of added salt was compared with that of Arnold and Overbeek (Rec. Trav. Chim. 1950,69 192) on the titration of poly(methacry1ic acid) in the presence of various amounts of added salts.It was concluded that the titration of humic acids from diverse sources would yield more reliable and comparable results if carried out in the presence of added salts of concentration greater than 0 . 0 5 ~ . The work of Puustjarvi ( A c t a Agric. Scand. 1955 5 257) has demonstrated a hysterisis effect in slow acid - base titrations of humic acids carried out under aerobic conditions. The lecturer proposed two possible explanations of this effect which were oxidative coupling of phenolic groups resulting in the formation of ether linkages and a reduction of the total acidity and/or absorption of carbon dioxide at high pH values during the course of the titration. It was recommended that acid - base titrations of humic acids should be carried out under anaerobic conditions.None of the methods for determining carboxylic acid groups in humic acids was regarded as very satisfactory but the best of these was considered to be the determination of the difference in total acidity before and after methylation with dimethyl sulphate. Purely chemical methods of determining phenolic hydroxyls of humic acids were considered to be extremely unsatisfactory and the lecturer presented some preliminary results of his work on oxidimetric titration of the phenolic groups with 0 . 0 5 ~ ammonium vanadate in molar ammonia the humic acids being in suspension in 5~ hydrochloric acid. The minimum duration of the titration for a successful end-point was 8 hours. The results of such titrations indicated the presence of about 2-45 milli-equivalents per g i.e.about one third of the total acidity of the humic acids examined. Knowledge of the structure and properties of humic acids was summarised. December 19661 DETERMINATION OF ORGANIC ACIDS 183 The Determination of Citric Acid BY A. R. WITTY (John and E. Sturge Ltd. Selby Yorkshire) MR. WITTY said that the widespread occurrence of citric acid in nature its increasing numbers of uses and its industrial production by fermentation processes had led to the development of a number of methods with many variants for determining citric acid for investigational and control purposes. The older methods usually based on the separation of citric acid by precipitation as an insoluble salt were not generally specific but in certain applications could provide satis- factory results.The conversion by oxidation and bromination to pentabromacetone provided a highly specific basis for a large group of methods for gravimetric titrimetric and colorimetric determinations of citric acid. The gravimetric version with various preliminary treatments was widely applicable and provided a most accurate method when more than 50 mg of citric acid were present in a suitable sample. Several titrimetric forms of the method existed in which the bromine of the pentabromace- tone was either liberated as bromine and titrated accordingly or displaced iodine for subse- quent iodimetric titration. These adaptations extended the application of the pentabromace- tone method to the submilligram level. Various modifications of a colorimetric method based on the conversion to pentabromace- tone extraction of the latter into an inert solvent and a colour-producing reaction with sodium sulphide extended the sensitivity to 10 ,ug of citric acid.A thiourea - borax reagent had been found to be more specific than sodium sulphide in its reaction with pentabromacetone and less susceptible to small variations in conditions. The improved method had a standard deviation of about 3 per cent. Other colour-developing agents used to react with pentabromacetone were iodide alkaline resorcinol and alkaline pyridine. These could be used to measure amounts of citric acid in the range of 0.5 to 40 pg with a precision of &5 per cent. Simple colorimetric methods for use with larger numbers of samples had been developed on the basis of the reaction between citric acid pyridine and acetic anhydride.The best precision of the reported versions was f 1 per cent. In all of the variants in the literature the additions of pyridine and acetic anhydride to the citric acid were made separately. A modification of the method of Saffran and Denstedt was described which had several distinct advantages over the existing pyridine - acetic anhydride methods and was of precision equal to the best of them. The whole procedure including colour measurements was carried out in glass-stoppered tubes with a single reagent containing both pyridine and acetic anyhydride. Other techniques of diverse natures had generally been of limited application often with precisions of the order of 510 per cent. The choice of method for a particular application in recent years had judging from the literature generally been one of the colorimetric methods based on the formation of penta- bromacetone and its extraction with an organic solvent or one of the variants of the pyridine - acetic anhydride method.The gravimetric version of the pentabromacetone method should in Mr. Witty’s opinion always be considered as it was capable of the greater precision. The standard deviations of the gravimetric pentabromacetone colorimetric pyridine - acetic anhydride and colorimetric pentabromacetone - alkaline pyridine method used to cover the range of concentrations encountered in a citric acid manufacturing process and research projects had been calculated from routine results as 0.33 0.98 and 3.7 per cent. respectively. Methods for determining isocitric acid were reviewed. 184 CHANGES IN THE REGISTER OF MEMBERS [PYOC. SOC. Analyt. Chew. Changes in the Register of Members NEW MEMBERS Robert George Blezard L.R.I.C.
