Abstract:
The present invention relates to a continuous alkaline washing method of resorcinol bis (bis -2, 6-dimethylphenyl phosphate), the crude product of resorcinol bis (bis -2, 6-dimethylphenyl phosphate) was obtained after two-step reaction of acylation and esterification, the mixed liquid is formed, continuously enters into the polymerization termination tank, and is subjected to sufficient alkali washing. The liquid in the polymerization termination tank is forcibly mixed by the pipeline pump, and after alkali washing, the mixed liquid enters into the cone sedimentation kettle for settlement, the bottom of the pot is controlled to discharge waste water, and the upper organic phase continuously enters the washing process through the top of the kettle. After thorough washing, the solvent is recovered by evaporation to obtain the finished product, the stability of product quality is maintained, the emulsification phenomenon and the phenomenon of entrainment of product liquid in drainage are effectively prevented, the corrosion of equipment is reduced, the pollution to the environment is reduced, and the cost is saved, the yield of the product was improved.
