New Compounds of Hydrazine with Fatty Acids


COMPOUNDS of several of the more important organic fatty acids with hydrazine, analogous to the aromatic hydrazides previously prepared, have been obtained by Prof. Curtius and his pupils Messrs. Schöfer and Schwan, and an account of them is published in the current issue of the Journal jür Praktische Chemie. The hydrazides of the monobasic fatty acids are distinguished from the aromatic analogues by their greater solubility in water. In all cases they are most advantageously prepared by reacting with one equivalent of hydrazine hydrate upon the ester of the acid rather than upon the free acid itself. The esters of dibasic fatty acids react analogously with two equivalents of hydrazine hydrate, producing hydrazides which contain two NHNH groups.
