摘要： A method of producing a purified ester-substituted phenol stream is provided. The method includes a first step of obtaining from a melt transesterification reaction a byproduct stream containing a residual ester-substituted diaryl carbonate, an ester-substituted phenol, a residual melt transesterification catalyst, and a catalyst degradation product. A second step includes treating the reaction byproduct stream to separate ester-substituted phenol and catalyst degradation product from residual ester-substituted diaryl carbonate and residual melt transesterification catalyst to create a light recycle stream containing ester-substituted phenol and catalyst degradation product and a heavy recycle stream containing residual ester-substituted diaryl carbonate and residual melt transesterification catalyst. A third step includes treating the light recycle stream to reduce catalyst degradation product concentration thereby producing a purified ester-substituted phenol stream.
摘要翻译：提供了一种生产纯化的酯取代的苯酚流的方法。该方法包括从熔融酯交换反应获得含有残留的酯取代的碳酸二芳酯，酯取代的酚，残余熔融酯交换催化剂和催化剂降解产物的副产物流的第一步骤。第二步包括处理反应副产物流以分离酯取代的苯酚和残留的酯取代的碳酸二芳酯和残余的熔融酯交换催化剂的催化剂降解产物，以产生含有酯取代的苯酚和催化剂分解产物的轻质循环物流和重循环含有残余酯取代的碳酸二芳基酯和残余熔体酯交换催化剂的流。第三步骤包括处理轻质循环物流以降低催化剂降解产物浓度，从而产生纯化的酯取代的苯酚流。

摘要： A method of preparing polycarbonate includes a steps of providing a melt reaction mixture and allowing the melt reaction mixture to react to build molecular weight, thereby preparing the polycarbonate. The melt reaction mixture has a dihydroxy compound, an ester substituted diaryl carbonate mixture, and a melt trans esterification catalyst where the ester substituted diaryl carbonate mixture may contain acidsubstituted phenol. The method also includes the step of adjusting the molar ratio of acid-substituted phenol, if present, to melt transesterification catalyst (acid-substituted phenol/catalyst) in the melt reaction mixture to an amount of less than 10.

摘要： An upflow reactor (10) for the production of bisphenol A from acetone and phenol includes a vessel (14), a catalyst bed (12) disposed within the vessel (14), and a reactant distribution/product collection system disposed within the vessel (14). The reactant distribution/product collection system includes a perforated distributor (20) disposed at a lower end of the reactor (10). The reactant distribution/product collection system further includes a perforated collector (40) disposed at an upper end of the reactor (10). A method for producing bisphenol A from acetone and phenol includes introducing the reacting mixture containing acetone and phenol to the distributor (20), directing it upward through the catalyst bed (12), and recovering the reacted acetone and phenol as bisphenol A together with other isomers and non reacted species. A method for avoiding catalyst bead carryover from the bed (12) in an upflow reactor includes receiving a product of the upflow reactor (10) into the collector (40) disposed at an upper end of the reactor (10) through a screen (47) with proper slit size.
