| titleOfInvention | Method of producing terephthalic acid |
| abstract | Provided are a terephthalic acid production method capable of efficiently obtaining terephthalic acid and controlling the particle size distribution of a crystal, and a terephthalic acid having a narrow particle size distribution. For this purpose, when terephthalic acid aqueous solution is refine | purified with a platinum group metal catalyst, and then crystallization of terephthalic acid from aqueous solution, crystallization is formed in substantially trapezoidal plate shape, and it performs in the stirring tank provided with the stirring blade which can change a rotation speed in the tank bottom. Thereby, terephthalic acid is obtained efficiently, and terephthalic acid crystal which is excellent in powder characteristic, slurry characteristic, and reactivity, and which can control particle size distribution of a crystal is obtained. |
