| 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 method for producing an aromatic polycarbonate by reacting an aromatic dihydroxy compound and a carbonic acid diester by a transesterification reaction using an alkali metal compound and / or an alkaline earth metal compound and a nitrogen-containing basic compound as a catalyst, An alkali metal compound and / or an alkaline earth metal compound in a solution state, After filtering the nitrogen-containing basic compound in a solution state with a filter, it is used for a melt polycondensation reaction. |
