| titleOfInvention | Isocyanate production method |
| abstract | An object of the present invention is to provide a method capable of stably producing an isocyanate with a high yield for a long period of time without producing various problems as in the prior art when producing an isocyanate without using phosgene. . The present invention is a method for producing an isocyanate by subjecting a carbamic acid ester to a pyrolysis reaction, the step of recovering a low boiling point component as a gas phase component from a pyrolysis reactor in which the pyrolysis reaction is performed, Recovering a liquid phase component containing a carbamate from the bottom of the pyrolysis reactor, and supplying a part or all of the liquid phase component to the top of the pyrolysis reactor. A manufacturing method is disclosed. |
