Reaction of diaminoglyoxime and cyclic azine compounds in high temperature and pressure water

Diaminoglyoxime was reacted in water at 150-400℃ and at 27.5 MPa pressure in metal Ti tubing reactor. Experimental results indicate that, diaminoglyoxime can be converted into NH-3 and CO-2, either through direct hydrolysis or through pyrolysis and polymerization, and then further hydrolysis. The possible reaction mechanism is nucleophilic addition of water.
