Abstract
Alkylesters of saturated aliphatic carboxylic acids are prepared by reacting aliphatic monoolefins containing internal double bonds and having 6 to 20 carbon atoms with carbon monoxide and an alkanol having one hydroxyl function in the presence of a catalyst of a cobalt compound and a promoter where the promoter is pyridine, a non-ortho-substituted alkylpyridine or a mixture thereof. The monoolefins can possibly contain paraffins and the reaction is carried out with: PA1 (a) a promoter to cobalt ratio of 3/1 to 25/1; PA1 (b) a cobalt concentration from 0.02 to 0.2 gram-atom of cobalt per mole of monoolefin; PA1 (c) a temperature between 165.degree. and 195.degree. C.; PA1 (d) a pressure from 150 to 300 bars; PA1 (e) a molar ratio of alkanol to monoolefin from 1/1 to 10/1; and PA1 (f) a dwell time exceeding 15 minutes.
