Apparatus for continuous liquid-phase oxidation reaction |
摘要 |
A reaction vessel for continuously producing an aromatic carboxylic acid sparingly soluble in a solvent by liquid-phase oxidizing a corresponding alkyl aromatic compound with a molecular oxygen-containing gas in the presence of a lower aliphatic carboxylic acid solvent and an oxidation catalyst. The adhesion of the aromatic carboxylic acid on the inside wall of the reaction vessel at the interface between the vapor-phase portion and the liquid-phase portion is prevented by locating in the reaction vessel a means such as a porous annular pipe for spraying onto the inside wall of the reaction vessel above the level of the reaction liquid a part of a solvent-catalyst mixture supplied continuously to the reaction vessel.
