Abstract:
Disclosed is a method for preparation of 1,1-diamino-2,2-dinitroethylene (DADNE) through the hydrolysis of 4,6-dihydroxy-5,5-dinitro-2-(dinitromethylene)-2,5-dihydropyrimidine (DHDNDP) obtained by the nitration of 4,6-dihydroxy-2-methylpyrimidine (DHMP), which can avoid eruption or sudden frothing of a reaction solution on a lab scale and even a large scale preparation as well as reduce the reaction time.
