AbstractThe kinetics of methylene diphenyl dicarbamate thermo-decomposition to diphenylmethane diisocyanate was investigated in the presence of diisooctyl sebacate. A consecutive reaction model was established by simplifying the thermo-decomposition process and two steps were conformed to be the first-order reaction by integral test model and numerical differential method, respectively. The results show that the activation energies of two steps are 138.82 and 167.78 kJ/mol, while the frequency factors are 1.51 x 10(12) and 5.33 x 10(14), respectively. Base on the obtained kinetic model, the reaction proceeding can be calculated in given conditions.; The kinetics of methylene diphenyl dicarbamate thermo-decomposition to diphenylmethane diisocyanate was investigated in the presence of diisooctyl sebacate.
