摘要:
AbstractA method is presented for the gravimetric determination of gold in alloys. Based on a known procedure used in metallurgy, it involves the separation of gold from the other elements constituting the alloy, by the aid of the “parting process”, suitably modified. It involves a relatively simple technique with a high degree of accuracy. Gold was successfully determined in the presence of the following metals: Ag, Cd, Cu, Cr, Fe, Mn, Ni, Pd, Sn, Zn.Platinum seriously interferes with the analy

摘要:
AbstractThe oxidation of anthracene, 9,9′‐bianthryl and 1,1,2,2‐tetraphenyl‐ 1,2‐bis (9,10‐dihydro‐anthracenyl‐9) ethane (TPDAE) by potassium chlorate and perchlorate, in the presence of vanadium pentoxide, was studied both by a batch method in closed ampoules and by gravimetry. The reactions took place with the participation of the gaseous phase while certain stages seem to be solid

摘要:
AbstractA new series of heterocyclic oximes, prepared by the quarternization of 4‐hydroximino‐methylpyridine with various aminoalkyl halides, have been tested as reactivators of phosphorylated cholinesterase. With the most active member, 4‐hydroximinomethyl‐l‐[3(N, N‐dimethylamino)‐n‐propyl]‐pyridinium chloride, the rate of reactivation is comparable to that obtained with the known diquarternary compound, TMB‐4. These findings shed new light on the mechanistic concept of the r
