  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.

• Metal cation-exchanged montmorillonite (Mn+-mont)-catalysed aromatic alkylation with aldehydes and ketones
  作者：Jun-ichi Tateiwa、Ei Hayama、Takahiro Nishimura、Sakae Uemura

  DOI：10.1039/a701744h

  日期：——

  The alkylation of aromatic compounds with aldehydes and ketones in the presence of a variety of metal cation-exchanged montmorillonites (Mn+-mont; Mn+ = Zr4+, Al3+, Fe3+, Zn2+, H+, Na+) has been investigated. Al3+- and Zr4+-Monts are revealed to be effective as catalysts, while no reaction takes place with Na+-mont. Al3+-Mont-catalysed alkylation of phenol with several aldehydes produces mainly or almost solely the corresponding gem-bis(hydroxyphenyl)alkanes (bisphenols) in good yields, while that with several ketones affords selectively the corresponding alkylphenols in moderate to good yields. The alkylation always occurs at the carbonyl carbon without any skeletal rearrangement and the kind of products depends much on the steric hindrance of an electrophilic intermediary carbocation. The alkylation of anisole, veratrole and p-cresol proceeds well, while that of toluene, benzene, chlorobenzene and nitrobenzene scarcely occurs.

  在各种金属阳离子交换的蒙脱石（Mn+-mont；Mn+ = Zr4+、Al3+、Fe3+、Zn2+、H+、Na+）存在下，研究了芳香化合物与醛和酮的烷基化反应。发现Al3+和Zr4+蒙脱石是有效的催化剂，而Na+蒙脱石则不发生反应。由Al3+蒙脱石催化的苯酚与几种醛的烷基化反应主要或几乎只生成了相应的双（羟苯基）烷烃（双酚），产率良好；而与几种酮的烷基化反应则选择性地生成了相应的烷基苯酚，产率适中至良好。烷基化总是发生在羰基碳上，没有骨架重排，产物的类型很大程度上取决于亲电中间体的碳正离子的空间位阻。茴香醚、邻苯二甲醚和对甲酚的烷基化反应良好进行，而甲苯、苯、氯苯和硝基苯的烷基化反应几乎不发生。
