摘要：
A process for controlling the regeneration of boron trifluoride catalyst complexes in the production of carboxylic acids and other products using boron trifluoride hydrates as a catalyst. Catalyst strength is determined by measuring the electrical conductivity of the catalyst recovered from hydrolysis. If the conductivity is greater than a predetermined value, the hydrolysis water rate is reduced and if the conductivity is less than a predetermined value, the hydrolysis water rate is increased. Conductivity is determined by a toroidal conductivity sensor and a control valve responsive to operation of the conductivity sensor serves to increase or decrease the flow rate accordingly.
摘要（中）：
一种控制三氟化硼催化剂络合物在使用三氟化硼水合物作为催化剂的羧酸和其它产物生产中的再生方法。 通过测量从水解回收的催化剂的电导率来确定催化剂强度。 如果导电率大于预定值，则水解水的速率降低，如果导电率小于预定值，则水解水的比率增加。 电导率由环形电导率传感器确定，并且响应于电导率传感器的操作的控制阀用于相应地增加或减小流量。
