METHOD FOR PRODUCING PHENOLIC COMPOUND |
摘要 |
A method is provided for producing an ester-substituted phenol product stream from an ester-substituted diaryl carbonate manufacturing waste stream. The method includes the steps of obtaining a waste stream containing an ester-substituted diaryl carbonate from an ester-substituted diaryl carbonate manufacturing facility and creating a reaction mixture by combining the waste stream with a solvent and with a transesterification catalyst. The reaction mixture is maintained at a reaction pressure at or below atmospheric pressure, and at a reaction temperature for a period of time sufficient to produce ester-substituted phenol by solvolysis of the ester-substituted diaryl carbonate. Ester-substituted phenol is removed from the reaction mixtures in an ester-substituted phenol stream. The solvent, the reaction temperature, and the reaction time are selected in combination such that less than 1,000 ppm of acid-substituted phenol is present in the ester-substituted phenol stream. |
