    • The present invention provides a reactor system for producing polycarbonate. The reactor system has one or more reactant vessels, an oligomerization reactor, a first pressure control device, a preheater, a second pressure control device, a distributor, and a flash tank. The one or more reactant vessels contain reactants contain a melt transesterification catalyst, a dihydroxy compound, and an activated diaryl carbonate. The reactor system is connected in the following configuration: (i) the one or more reactant vessels connected to the oligomerization reactor, (ii) the first pressure control device disposed between and connecting the outlet of the oligomerization reactor and the inlet of the preheater; (iii) the second pressure control device disposed between and connecting the outlet of the preheater and the distributor; and (iv) the distributor disposed at the inlet to the flash tank. The pressure in the preheater is controllable at a pressure intermediate between the pressure in the oligomerization reactor and the flash tank.
    • 本发明提供了一种用于生产聚碳酸酯的反应器系统。 反应器系统具有一个或多个反应物容器,低聚反应器,第一压力控制装置,预热器,第二压力控制装置,分配器和闪蒸罐。 一个或多个反应物容器包含含有熔体酯交换催化剂,二羟基化合物和活化的碳酸二芳基酯的反应物。 反应器系统以如下结构连接:(i)连接到低聚反应器的一个或多个反应容器,(ii)设置在低聚反应器的出口和预热器入口之间并连接低聚反应器的出口的第一压力控制装置; (iii)所述第二压力控制装置设置在所述预热器和所述分配器之间并连接所述预热器的出口; 和(iv)布置在闪蒸罐的入口处的分配器。 预热器中的压力可以在低聚反应器和闪蒸罐中的压力之间的压力下控制。
