Method and apparatus for preparing polycarbonate |
| abstract |
The present invention relates to the method for preparing polycarbonate, comprise at least following steps: released hydroxyaryl reaction product, b) subjecting the transesterified reaction product to precondensation in at least one precondensation reactor while continuously removing the released hydroxyaryl reaction product, c) subjecting the precondensed reaction product to at least one The polycondensation is carried out in a polycondensation reactor in which the removal of the aryl reaction products during the transesterification and the removal of the hydroxyaryl reaction products during the precondensation takes place through a common column in which the entrained diaryl carbonate The ester is separated from the withdrawn hydroxyaryl reaction product. |
