Method for increasing yield and product quality while reducing power costs in oxidation of an aromatic alkyl hydrocarbon to an aromatic carboxylic acid

摘要

A continuous stirred-tank reactor suitable for the liquid-phase oxidation of an aromatic alkyl to an aromatic carboxylic acid is provided with vertically disposed, relatively narrow baffles on the reactor wall and with oxidizing gas inlet means below the agitator in the reactor. The baffle width is about 0.02 to about 0.04 times the diameter of the reactor.
