The kinetics of the decomposition of dimethylhexane-1,6-dicarbamate to 1,6-hexamethylene diisocyanate was studied. A consecutive reaction model was established and the reaction orders for the two steps were confirmed to be 1 and 1.3 by the integral test method and the numerical differential method, respectively. The activation energies of the two steps were (56.94 ± 5.90) kJ·mol− 1 and (72.07 ± 3.47) kJ·mol− 1 with the frequency factors exp(12.53 ± 1.42) min− 1 and (14.254 ± 0.84) mol− 0.33·L0.33·min− 1, respectively. Based on the kinetic model obtained, the progress of the reaction can be calculated under given conditions.
