| titleOfInvention | process for the production of aromatic polycarbonate |
| abstract | "PROCESS FOR PRODUCING AROMATIC POLYCARBONATE". This is a method for handling the phenol byproduct produced in a PC production step. In the method, the water content of the phenol byproduct is set to a value within a given range. Thus, production efficiencies in the BPA production stage and the DPC production stage to which the phenol by-product is to be sent are maintained, thus maintaining a PC production efficiency throughout the process. The process for producing an aromatic polycarbonate comprises a diphenyl carbonate production step, a bisphenol A production step, and an aromatic polycarbonate production step, and is characterized by the amount of water contained in the phenol by-product recovered in the step. of aromatic polycarbonate production is regulated by 0.2% or less and the phenol by-product thus regulated is used as a feedstock for the diphenyl carbonate production step and / or bisphenol A production step. |
