  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。

  Disclosed is a process for producing an aromatic carbonate which comprises transesterifying, in the presence of a metal-containing catalyst, a starting material selected from the group consisting of a dialkyl carbonate, an alkyl aryl carbonate and a mixture thereof with a reactant selected from the group consisting of an aromatic monohydroxy compound, an alkyl aryl carbonate and a mixture thereof, wherein the transesterification is conducted while maintaining a weight ratio (WR) of at least one aromatic group-containing substance selected from the group consisting of a specific aromatic polyhydroxy compound and a residue thereof to the metal of the metal-containing catalyst at 2.0 or less, wherein the weight ratio (WR) is measured with respect to a catalyst-containing liquid-phase mixture in a system for the transesterification, and wherein the aromatic group-containing substance originates from the starting material, the reactant and/or a by-product of the transesterification. According to the process of the present invention, the transesterification reaction can be conducted without suffering disadvantageous phenomena, such as the deposition of the catalyst from the catalyst-containing liquid-phase mixture and the adhesion of the deposited catalyst to the inner walls of the reactor, pipes and the like, so that the desired aromatic carbonate can be produced stably for a prolonged period of time.

  本发明公开了一种生产芳香族碳酸酯的工艺，该工艺包括在含金属催化剂存在下，将选自由碳酸二烷基酯、碳酸烷基芳基酯及其混合物组成的组的起始原料与选自由芳香族单羟基化合物组成的组的反应物进行酯交换反应、碳酸烷基芳基酯及其混合物，其中酯交换反应是在至少一种选自由特定芳香族多羟基化合物及其残余物组成的组中的含芳香族基团物质与含金属催化剂的金属的重量比(WR)保持在2.0或更低，其中重量比(WR)是相对于用于酯交换反应的系统中含催化剂的液相混合物而测量的，并且其中含芳香族基团物质来源于起始原料、反应物和/或酯交换反应的副产物。根据本发明的工艺，在进行酯交换反应时，不会出现催化剂从含催化剂的液相混合物中沉积以及沉积的催化剂附着在反应器内壁、管道等处等不利现象，从而可以长期稳定地生产出所需的芳香族碳酸盐。
