titleOfInvention | Method for producing aromatic polycarbonate |
abstract | A subject for the invention relates to a method for coping with by-product phenol in which the water content of the by-product PL generated in a PC production step is limited to a value in a given range to thereby maintain a production efficiency in the BPA production step and DPC production step to which the by-product PL is sent, whereby the overall efficiency of PC production is maintained. The invention is a process for producing an aromatic polycarbonate which comprises a diphenyl carbonate production step, a bisphenol A production step, and an aromatic polycarbonate production step, and is characterized in that the amount of water contained in the by-product phenol recovered in the aromatic polycarbonate production step is regulated to 0.2% by weight or smaller and this phenol is used as a starting material in the diphenyl carbonate production step and/or the bisphenol A production step. |
