PEP Review 77-2-3

Toluene Diisocyanate by Carbonylation Process via Urethane

Published: May 1978

Dinitrotoluene (DNT) reacts with methyl alcohol and carbon monoxide in the presence of a selenium catalyst to form diurethane, which can be decomposed to toluene diisocyanate (TDI). A process is evaluated based on this route. It is found that the capital investment for this process will be higher than that for the conventional process for making TDI from DNT and phosgene, but that the production cost will be approximately the same as that for the conventional process if HCl by-produced in the latter process is not credited.
