Abstract

A process and apparatus for the continuous production of alkylesters of saturated aliphatic carboxylic acids by reacting olefins with carbon monoxide and alkanol in the presence of a catalyst consisting of a cobalt compound and a promoter selected from the group consisting of pyridine, non-ortho-substituted alkylpyridines and mixtures at elevated pressure and elevated temperature, the reaction based on olefins having at least 8 C atoms and being carried out in a reactor wherein the flow characteristic is adjusted so that tubular flow without back-mixing predominates, and wherein the raw materials are supplied in the desired ratios at the input side of the reactor.
