This invention relates to a process for the chlorination of phthalic anhydride. Many metallic chlorides as well as some nonmetallic chlorides have been recognized as effective chlorine carriers or catalysts for the direct chlorination of organic compounds. Among these may be included the chlorides......
CHLORINATION OF PHTHALIC ANHYDRIDEGERALD A. THOMASPAUL W. BLUME
This invention relates to the manufacture of chloro-derivatives of phthalic anhydride and it deals more particularly with a method of direct chlorination of the anhydride with elemental chlorine. Heretofore various methods for the manufacture of tetrachlorophthalic acid or its anhydride have......
