ABSTRACT:
A process and a device for the catalytic hydrolysis of a carboxylate, e.g., methyl acetate, ethyl acetate, i- or n-propyl acetate, i- or n-butyl acetate, allyl acetate and methyl formate, into the corresponding carboxylic acid and alcohol, by a combination of a pre-reactor and a reactive distillation column are disclosed. By the combination of a pre-reactor and a reactor distillation column, the conversion ratio can be substantially improved. The device can compensate for fluctuations in the supply quantity or in the composition of the feed flow. The product composition can also be controlled in a wide range.
