By use of several kinds of aliphatic and armatic acid hydrazides, reactions between acid hydrazides and that of acid hydrazide and acid amide were carried out.Unreacted components were determined by the method given in this first report and the reactiveness in each case has been investigated. It was confirmed that the reaction for formation of aminotriazole from acid hydrazide was the second order reaction. The reaction velocity constant was greater in those having less carbon atoms in case of aliphatic compounds while the reaction velocity was greater in those having more carbon atoms in aromatic acid hydrazides having 6, -40 carbon atoms. With the assumption that the reaction for formation of triazole from acid amide and acid hydrazide is similarly the second order reaction, the velocity ratios for formation of aminotriazole and triazole were investigated and found that the rate of formation of triazole was slower than aminotriazole.
