Method for cleaving polycarbonates to form bisphenols and diaryl carbonates |
| abstract |
(57) [Summary] [Purpose] A method of cleaving polycarbonates to produce bisphenols and diaryl carbonates by transesterification with phenols in the presence of a catalyst. This method isolates bisphenols from transesterification products and flash distills the remaining mixture containing phenols and diaryl carbonates. The phenols and diaryl carbonates are distilled off and separated, and the diaryl carbonates are recovered. |
