Dimethylhexane-1,6-dimethyleurethane is the key material for preparation of 1,6-hexamethylene diisocyanate by non-phosgene route. Our work mainly focuses on the study of the catalytic performances of metal oxysalts and metal oxides for the ammonolysis of DMC to HDU-M. Experiment effect showed the ammonolysis was omposed by two steps, in which the first step was easier to occur than the second.
