PROCESS FOR PRODUCTION OF 1,1'-DIMETHYL-5,5'-BITETRAZOLE

摘要

A manufacturing method of 1,1'-dimethyl-5,5'-bitetrazole is provided to shorten a reaction time, to improve yield and to be manufactured inexpensively. A manufacturing method of 1,1'-dimethyl-5,5'-bitetrazole comprises steps of: forming intermediate by reacting N,N'-dimethyl oxamide and acetonitrile in a solvent including acetonitrile; and cyclizing it by adding sodium azide to the intermediate. The first step and the second step are performed at a temperature of 20~30°C and a same reactor.
