2018101882 30 Nov 2018 p-toluenesulfonic acid for the cyclization reaction, added cyclization reaction terminator after cyclization reacted for 2-3 h. Transferred the product to scrubber L101, added water and stirred fully, washed the reactor, made the metal impurities and the catalyst enter into the water layer for separation. Concentrated the washed product 5 in concentrator L102. Added the concentrated product into glue mixer D103, then added an appropriate amount of cross-linking agent, stabilizer for glue mixing, compounded the glue with a certain viscosity to meet the requirements. Filtered the glue through filter LI03 and obtained the finished product. The advantages of this invention are that the reaction time is reduced and the reaction rate is improved.
