| titleOfInvention | Continuous production method of aromatic dicarboxylic acid |
| abstract | 【Task】 A continuous process for the production of aromatic dicarboxylic acids that can stabilize the progress of oxidation reaction for the first time, produce a product dicarboxylic acid with stable quality, and continue the oxidation reaction that saves resources and saves energy. It is to provide. [Solution] (1) In preparing the reaction solvent using at least a part of the separation mother liquor of the generated dicarboxylic acid, after measuring the catalyst concentration in the mother liquor in advance, by feedforward control (regardless of the water content), The concentration of the oxidation catalyst is stably prepared. (2) A predetermined amount of the solvent and the raw material aromatic hydrocarbon is continuously supplied to the oxidation reaction tank to cause an oxidation reaction with molecular oxygen gas, and the water concentration of the reaction tank condensed reflux is measured. The dicarboxylic acid is produced by stabilizing the water concentration in the reaction system by controlling the amount of the condensed reflux liquid extracted. (3) The stable holding of the temperature in the oxidation reaction is adjusted by the pressure, and the stable holding of the oxygen concentration in the exhaust gas is adjusted by the supply amount of the oxygen-containing gas.
