    • An object of the present invention is to provide a process that enables isocyanate to be produced stably over a long period of time and at high yield without encountering problems of the prior art during production of isocyanate without using phosgene. The present invention discloses a process for producing an isocyanate by subjecting a carbamic acid ester to a thermal decomposition reaction, including the steps of: recovering a low boiling point component in a form of a gaseous phase component from a thermal decomposition reaction vessel in which the thermal decomposition reaction is carried out; recovering a liquid phase component containing a carbamic acid ester from a bottom of the thermal decomposition reaction vessel; and supplying all or a portion of the liquid phase component to an upper portion of the thermal decomposition reaction vessel.
    • 本发明的目的是提供一种能够在长时间和高收率下稳定地制备异氰酸酯的方法,而不会在不使用光气的情况下在异氰酸酯的生产过程中遇到现有技术的问题。 本发明公开了一种通过使氨基甲酸酯进行热分解反应来制造异氰酸酯的方法,包括以下步骤:从热分解反应容器中回收气相成分形式的低沸点组分,其中 进行热分解反应; 从热分解反应容器的底部回收含有氨基甲酸酯的液相成分; 并将全部或一部分液相成分供给到热分解反应容器的上部。
