METHOD FOR REMOVING IMPURITIES FROM PHENOL

摘要

PURPOSE: A method for eliminating phenol impurities is provided to minimize costs required for operational processes and replace energy multi-consumable processes using an ion-exchange resin reactor. CONSTITUTION: A method for eliminating phenol impurities includes the following: A phenol mixture containing one selected from hydroxyl acetone, 2-methyl benzo furan, and mesityl oxide is treated using bases and oxidizing chemicals. The treated phenol mixture is reacted in a reactor of 65-95 degrees Celsius. The reactor is filled with ion-exchange resins. One or more selected from hydroxyl acetone, 2-methyl benzo furan, and mesityl oxide is converted into a material of a high boiling point. The generated material of the high boiling point is eliminated through a distilling process to obtain high purity phenol.
