Process for purifying monotertiarybutyl-butylhydroquinone.

摘要

A SUPPLIED FOR PRODUCING TERTIARY BUTYL HYDROQUINONE FEED GRADE FROM A PROCESS monotertiary IMPURA butyl hydroquinone. CRYSTALS butyl hydroquinone monotertiary IMPURA are stirred at an elevated temperature while they are in contact with a nonpolar solvent under extraction conditions MOST DIRT FOLLOWED BY A SEPARATION OF CRYSTALS butyl hydroquinone monotertiary purified from solvent A temperature above the crystallization point of the impurities.
