    • The invention provides a process for the continuous production of bisphenol-A by continuously reacting phenol using an acid catalyst resin and continuously or essentially continuously removing water from the system. Continuous removal of water allows for increased catalytic activity of the resin and therefore improved productivity. Removal is facilitated by conducting the process in a carousel simulated moving bed device. Process efficiency is further enhanced by conducting the process in a device configured to have a combination of series, parallel or reverse flows which are optionally arranged so the process results in higher yield and lower impurities.
    • 本发明提供了一种通过使用酸催化剂树脂连续反应苯酚并连续或基本上连续地从体系中除去水来连续生产双酚A的方法。 持续去除水允许增加树脂的催化活性,从而提高生产率。 通过在旋转木马模拟移动床装置中进行该过程来促进移除。 通过在配置为具有串联,并联或逆流的组合的装置中进行该方法进一步提高了工艺效率,该组合可选地布置,使得该方法产生较高的产率和较低的杂质。

    • The invention concerns a method for separating fractions of a mixture using a chromatography device. The method includes the following steps: controlling in one node of the device, the history of a specific variable of the fractions of the mixture to be separated; detecting one characteristic point of the history, the characteristic point being between two successive steps of fraction collecting; comparing the position of the characteristic point relative to a target position; adjusting the amount of mobile phase modifying the position of the characteristic point to cause the position of the characteristic point to coincide with the target position. The invention also concerns a device for implementing the method. The method enables the operation of the device to be automatically set.
    • 本发明涉及使用色谱装置分离混合物的馏分的方法。 该方法包括以下步骤:在设备的一个节点中控制要分离的混合物的分数的特定变量的历史; 检测历史的一个特征点,特征点在分级收集的两个连续步骤之间; 比较特征点相对于目标位置的位置; 调整移动相位的量,改变特征点的位置,使得特征点的位置与目标位置一致。 本发明还涉及一种用于实现该方法的装置。 该方法使得能够自动设置设备的操作。
