METHOD FOR REDUCING MICROCONTAMINANTS DURING SYNTHESIS OF PENTACHLOROPHENOL |
摘要 |
A method for reducing contaminants during synthesis of pentachlorophenol includes providing a phenol-based starting material and a catalyst, which form a reaction mixture. A chlorine flow is introduced so that it is in contact with the reaction mixture, and the starting material and chlorine are reacted via a temperature-programmed reaction. The chlorine flow is terminated at a predetermined temperature prior to an end of the temperature-programmed reaction and/or at a point where the yield of pentachlorophenol is less than about 95%. |
