IMPROVED PROCESS FOR THE PREPARATION OF 5-AMINOTETRAZOLE

摘要

The compound 5-aminotetrazole is prepared by a process which comprises (a) reacting a hydrazine salt of a mineral acid with cyanamide to form the corresponding aminoguanidine salt, (b) diazotizing the aminoguanidine salt to the corresponding guanylazide salt, and (c) cyclizing the guanylazide salt to 5-aminotetrazole.
