Method for producing isocyanate |
| abstract |
(57) [Summary] [Structure] (1) A method for producing isocyanates characterized by thermally decomposing urethane in the presence of a carbamate represented by the formula (1). [Effect] In producing isocyanate by thermally decomposing carbamic acid ester, high yield and high selectivity, Moreover, the generation of insoluble polymer during the reaction is extremely small, and stable operation can be performed for a long time. |
