  摘要：

  AbstractA series of organic carbonates derived from mid‐, long‐chain, and Guerbet alcohols were synthesized in good yield (69–80% isolated yields after purification by distillation or recrystallization) though a carbonate interchange reaction by heating the linear or Guerbet alcohols with diethyl carbonate in the presence of catalyst, n‐dibutyltin oxide. The carbonates were isolated by Kügelrohr distillation or recrystallization from acetone and characterized using FTIR, GC, 1H and 13C NMR spectroscopy, and GC‐MS. El and positive Cl mass‐spectral techniques were used to characterize the carbonates. Such materials are currently of commercial interest as lubricants and additives in various industrial applications.

  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.

  本发明的一个目的是提供一种能够在长时间内稳定地高产且不使用光气的情况下生产异氰酸酯的方法，而不会遇到先前生产异氰酸酯时的问题。本发明公开了一种通过将氨基甲酸酯经受热分解反应来生产异氰酸酯的方法，包括以下步骤：从进行热分解反应的反应釜中回收形成气相组分的低沸点组分；从热分解反应釜底部回收含有氨基甲酸酯的液相组分；并将全部或部分液相组分供给至热分解反应釜的上部。

  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 provides an isocyanate production process including the steps of: obtaining a reaction mixture containing an aryl carbamate having an aryl group originating in a diaryl carbonate, an aromatic hydroxy compound originating in a diaryl carbonate, and a diaryl carbonate, by reacting a diaryl carbonate and an amine compound in the presence of a reaction solvent in the form of an aromatic hydroxy compound; transferring the reaction mixture to a thermal decomposition reaction vessel; and obtaining isocyanate by applying the aryl carbamate to a thermal decomposition reaction, wherein the reaction vessel in which the reaction between the diaryl carbonate and the amine compound is carried out and the thermal decomposition reaction vessel for the aryl carbamate are different.
