PROCESS AND DEVICE FOR HYDROLYTICALLY OBTAINING A CARBOXYLIC ACID AND ALCOHOL FROM THE CORRESPONDING CARBOXYLATE

摘要

The present invention relates to a process and to 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 means of a combination of a pre-reactor (13) and a reactive distillation column (15). By the combination of a pre-reactor (13) and a reactive distillation column (15), the conversion ratio can be substantially improved. The device furthermore makes it possible to 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.
