| titleOfInvention | Process for the production of 3- or 5-amino-1, 2, 4-triazoles |
| abstract | 3- or 5-Amino-1 : 2 : 4-triazole and 5- or 3-(C1-C3)-alkyl derivatives thereof are produced by heating in an organic solvent capable of entraining water an acyl-aminoguanidine or salt thereof, or a mixture of an aminoguanidine salt with a fatty acid containing not more than 4 carbon atoms, the water formed during the reaction being continuously removed together with the entraining agent by distillation. Specified entraining agents are toluene, xylene and iso-octane. Specified fatty acids are formic, acetic and butyric acids. The reaction is preferably conducted at 100-150 DEG C. and in presence of basically reacting substances such as amines (e.g. dimethylaniline). Amino- and acylamino-guanidine hydrochlorides and sulphates yield the corresponding aminothiazole hydrochlorides and sulphates, from which the free bases are obtained by further treatment; aminoguanidine bicarbonate, acylaminoguanidines and bicarbonates thereof yield the free bases directly. The examples describe the preparation of 3-amino-, 3-amino-5-methyl- and 3 - amino - 5 - n - propyl - 1 : 2 : 4 - triazoles. Specification 520,394, [Group IV], is referred to. |
