| titleOfInvention | Method for producing halophthalic acid and halophthalic anhydride |
| abstract | A process for producing halophthalic acid comprising contacting one or more halogen-substituted o-xylenes with oxygen and acetic acid in a liquid phase reaction mixture in the presence of a catalyst system at a temperature in the range of about 120 to about 220 ° C. Thus, less than about 10% halogen-substituted o-xylene starting material, halophthalic acid product, and less than about 10,000 ppm halobenzoic acid and less than about 1000 ppm based on the total amount of halophthalic acid present in the product mixture Disclosed is a method for obtaining a product mixture comprising a halophthalide byproduct of In addition, a method for producing halophthalic anhydride and a method for recovering high purity acetic acid from an aqueous acetic acid stream containing HCl produced during the production of halophthalic acid are also disclosed.
