| 摘 要： | 介绍了碳酸二甲酯(DMC)法合成聚碳酸酯(PC)的研究现状,指出DMC法合成PC需要解决的关键问题是合成二甲氧基碳酸双酚A二酯(DmC(1)),并剖析了DmC(1)选择性合成的主要影响因素。综述了DmC(1)合成催化剂的研究现状,指出提高DmC(1)收率和选择性的主要方法是制备合适的催化剂,分析了催化剂结构和表面性能对双酚A与DMC发生甲氧基羰基化和甲基化反应的影响,得出介孔载体内部负载有机氧化锡是催化DmC(1)选择性合成的重要手段。阐述了DMC法合成PC的主要影响因素,分析了缩聚反应过程。同时对DMC法合成PC的前景和该工艺存在的问题进行了评述。

| Abstract: | Research progresses in synthesis of polycarbonate(PC) from dimethyl carbonate(DMC) were introduced.Selective synthesis of the intermediate two-methylcarbonate-ended-bisphenol A(DmC(1)) from DMC were discussed.It was found that preparation of the suitable catalysts was the main way for increase of the selectivity and yield of DmC(1).The effects of the texture and surface properties of the catalysts on the carboxymethylation and methylation of bisphenol A with DMC were discussed.It was put forward that loadin... |
