Industrial synthesis of polycarbonate is mainly interfacephosgenation route. Bisphenol A is used as raw material, phosgene,sodium hydroxide and dichloromethane are used as raw materials andreaction AIDS. The process is mature, the product quality is high,and it is easy to scale and continuous production with goodeconomy. Therefore, this process has long occupied a leadingposition in the production of polycarbonate. However, because theraw material phosgene used in this process is highly toxic, manycompanies have studied non phosgene production routes in recentyears. In 1993, the non phosgene process was successfully studiedand industrialized by GE Plastics Japan
聚碳酸酯工业化合成主要是界面光气化路线，以双酚A为原料，使用光气、氢氧化钠和二氯甲烷为原料及反应助剂，此法工艺成熟，产品质量较高，易于规模化和连续化生产，经济性好。此工艺路线长期占据着聚碳酸酯生产的主导地位。但由于该法使用的原料光气剧毒，近年来各大公司纷纷研究非光气法生产路线。1993年非光气法工艺研究成功，并由GE塑料日本公司实现了工业化生产
