| titleOfInvention | Process and plant for the production of polycarbonate |
| abstract | The invention relates to a process for producing a polycarbonate, comprising at least the following steps: a) transesterification of one or more bisphenols with one or more diaryl carbonates in at least one transesterification reactor with continuous removal of the liberated hydroxy-aryl reaction product, b) pre-polycondensation of the reaction product of the transesterification in at least one pre-polycondensation reactor with continuous removal of the liberated hydroxy-aryl reaction product, c) polycondensation of the reaction product of the pre-polycondensation in at least one polycondensation reactor, wherein the removal of the aryl reaction product during the transesterification reaction and the removal of the hydroxy-aryl reaction product during the pre-polycondensation reaction via a common column, wherein entrained diaryl carbonate is separated from the withdrawn hydroxyaryl reaction product. |
