| titleOfInvention | Method for producing high-purity isophthalic acid |
| abstract | (57) [Summary] [Purpose] A method for producing isophthalic acid, which is a product from crude isophthalic acid obtained by liquid-phase oxidation of metaxylene with molecular oxygen, has high purity and high yield, and minimizes wastewater load. Develop a limited industrial method. [Structure] In crude isophthalic acid containing various impurities, It is characterized by a combination of hydrotreatment, crystallization separation, and extraction of mother liquor with meta-xylene. |
