| titleOfInvention | Method and device for producing aromatic carboxylic acid |
| abstract | (57) [Abstract] [Purpose] Aromatic carboxylic acids of high quality, especially the hue of product powder and good light transmittance when dissolved in an alkaline aqueous solution, do not increase the decomposition of the reaction solvent and cause explosion. Manufacture safely while avoiding danger. [Structure] A solvent containing a lower aliphatic carboxylic acid, an alkylbenzene, and a catalyst are reacted from a raw material introduction path 6, and a high-concentration oxygen-containing gas containing molecular oxygen at a higher concentration than air is reacted from a high-concentration oxygen-containing gas supply path 3. It is introduced into the vessel 1 and the alkylbenzene is subjected to liquid phase oxidation. Vapor discharge path 5 from reactor The steam is extracted through the heat exchanger 11, cooled in the heat exchanger 11, and separated in the separator 12 into the condensate and the exhaust gas from which the condensable components have been removed. The condensate circulates from the condensate circulation path 7 to the reactor 1. Part of the exhaust gas circulates from the gas circulation path 8 to the liquid phase portion of the reactor 1. |
