| titleOfInvention | Method for producing high-purity terephthalic acid |
| abstract | (57) [Summary] In a method for producing high-purity terephthalic acid using a mother liquor replacement device, an economic loss associated with the treatment of a raw water solvent discharged from the mother liquor replacement device after the catalytic hydrogenation treatment is reduced. SOLUTION: A crude terephthalic acid obtained by subjecting a p-phenylene compound to liquid phase oxidation is subjected to catalytic hydrogenation treatment in an aqueous solvent, and the mother liquor is replaced with a raw water solvent slurry of terephthalic acid obtained by sequentially reducing the pressure and temperature. The raw water solvent is replaced with water supplied to the tower from the bottom of the tower, and the raw water solvent flowing out from the top of the tower is cooled to 40 ° C. or less under reduced pressure, and the crystallized organic matter is filtered off. |
