| titleOfInvention | Method for producing terephthalic acid and terephthalic acid |
| abstract | A terephthalic acid production method capable of efficiently obtaining terephthalic acid and controlling the particle size distribution of crystals, and terephthalic acid having a narrow particle size distribution are provided. For this purpose, when the aqueous solution of terephthalic acid is purified with a platinum group metal catalyst, and then the terephthalic acid is crystallized from the aqueous solution, a stirrer blade having a substantially trapezoidal plate shape and capable of changing the number of revolutions is provided at the bottom In the stirring tank provided in Thus, terephthalic acid can be obtained efficiently, and terephthalic acid crystals having excellent powder characteristics, slurry characteristics, and reactivity and capable of controlling the crystal grain size distribution can be obtained. |
