摘要

Abstract

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.
