| Abstract: | This paper reviewed 4 kinds of currently commercialized technologies for producing polycarbonate (PC) and elucidated the process flow and characteristics of each technology. The key equipment in polycondensation phase of non-phosgene process was emphatically introduced. The non-phosgene technology for preparing PC was gradually establishing its preponderance in the competition with the traditional phosgene process. The further effort was predicted to be needed in the future to optimize the design of reactors in transesterification and polycondensation phase. |
