AbstractThe 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 center dot mol(-1) and (72.07 +/- 3.47) kJ center dot mol(-1) with the frequency factors exp(12.53 +/- 1.42) min(-1) and (14.254 +/- 0.84) mol(-0.33) center dot L-0.33 center dot min(-1), respectively. Based on the kinetic model obtained, the progress of the reaction can be calculated under given conditions.
