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

Diaminoglyoxime was reacted in water at 150–400°C and at 27.5 MPa pressure in metal Ti tubing reactor. Experimental results indicate that, diaminoglyoxime can be converted into NH₃ and CO₂, either through direct hydrolysis or through pyrolysis and polymerization, and then further hydrolysis. The possible reaction mechanism is nucleophilic addition of water.
