The work describes the existing isocyanate-obtaining processes and the main problems in the study of isocyanate synthesis by the thermal decomposition of carbamates, which can be solved using mathematical and computer models. Experiments with carbamates of various structures were carried out. After processing the experimental data, the activation energy and the pre-exponential factor for isocyanate synthesis by the thermal decomposition of carbamates were determined. Then, a mathematical model of the reactor for the thermal decomposition of carbamates using the COMSOL Multiphysics software was developed. For this model, computational experiments under different conditions were carried out. It was shown that the calculation results correspond to the experimental ones, so the suggested model can be used in the design of the equipment for isocyanate synthesis by the thermal decomposition of carbamates.<\/jats:p>","DOI":"10.3390\/computation8040089","type":"journal-article","created":{"date-parts":[[2020,10,18]],"date-time":"2020-10-18T21:26:06Z","timestamp":1603056366000},"page":"89","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Modeling of Isocyanate Synthesis by the Thermal Decomposition of Carbamates"],"prefix":"10.3390","volume":"8","author":[{"given":"Ratmir","family":"Dashkin","sequence":"first","affiliation":[{"name":"Engineering Center, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgii","family":"Kolesnikov","sequence":"additional","affiliation":[{"name":"Engineering Center, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pavel","family":"Tsygankov","sequence":"additional","affiliation":[{"name":"International Science and Education Center for Transfer of Biopharmaceutical Technologies, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Igor","family":"Lebedev","sequence":"additional","affiliation":[{"name":"International Science and Education Center for Transfer of Biopharmaceutical Technologies, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6765-7563","authenticated-orcid":false,"given":"Artem","family":"Lebedev","sequence":"additional","affiliation":[{"name":"International Science and Education Center for Transfer of Biopharmaceutical Technologies, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Menshutina","sequence":"additional","affiliation":[{"name":"International Science and Education Center for Transfer of Biopharmaceutical Technologies, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khusrav","family":"Ghafurov","sequence":"additional","affiliation":[{"name":"Engineering Center, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abakar","family":"Bagomedov","sequence":"additional","affiliation":[{"name":"Engineering Center, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sonnenschein, M.F.
