| titleOfInvention | Method for recovering catalyst from reaction mixture solution containing diaryl carbonate |
| abstract | (57) [Summary] (Modifications) [PROBLEMS] A method for recovering a catalyst from a diaryl carbonate-containing reaction mixed solution, wherein a catalyst-containing mother liquor is transferred to a reactor for producing diaryl carbonate without inactivation. The present invention provides a method for recirculation. (I) (wherein, R represents a C6-15 aryl group) an oxidative carbonylation reaction of an aromatic hydroxy compound represented by the following formula (II): R-O-CO- The reaction mixture solution containing a diaryl carbonate represented by OR (II) (wherein R is the same as defined in the formula (I)) is flash-separated to remove water, and then the solvent used in the carbonylation reaction is removed. A crystallization operation is performed by adding the same solvent to the bottoms, and the diaryl carbonate is selectively crystallized and recovered, The mother liquor (C) containing the catalyst is recycled to the reactor for producing the diaryl carbonate, and the catalyst from the reaction mixture solution containing the diaryl carbonate is recovered. |
