Аннотация:The presented work is devoted to isocyanate synthesis by the thermal decomposition ofcarbamates model. The work describes the existing isocyanate-obtaining processes and the mainproblems in the study of isocyanate synthesis by the thermal decomposition of carbamates, whichcan be solved using mathematical and computer models. Experiments with carbamates of variousstructures were carried out. After processing the experimental data, the activation energy and thepre-exponential factor for isocyanate synthesis by the thermal decomposition of carbamates weredetermined. Then, a mathematical model of the reactor for the thermal decomposition ofcarbamates using the COMSOL Multiphysics software was developed. For this model,computational experiments under different conditions were carried out. It was shown that thecalculation results correspond to the experimental ones, so the suggested model can be used in thedesign of the equipment for isocyanate synthesis by the thermal decomposition of carbamates.
