| titleOfInvention | Method for producing aromatic polycarbonate |
| abstract | (57) [Summary] [PROBLEMS] To provide a method for producing a polycarbonate resin having excellent quality by using a transesterification method which has no environmental problems and is excellent in economic efficiency. SOLUTION: A plurality of reactors including one or more vertical reaction tanks are installed in series to transesterify an aromatic dihydroxy compound and a carbonic acid diester in the presence of a catalyst to continuously produce an aromatic polycarbonate. In the method, after the mixture to be reacted in at least one vertical reaction tank is previously heated to an internal temperature of −50 ° C. or higher and + 20 ° C. or lower, the upper part of the operating liquid level of the vertical reaction tank is And it is supplied near the operating liquid level. |
