Abstract
Process for the production of a saturated aliphatic monocarboxylic acid isopropyl ester having 2 to 4 carbon atoms in its molecule, alone or accompanied by isopropanol, by heating, in the presence of acetic acid and steam, of a resulting mixture of the absorption of propylene in aqueous sulfuric acid, characterized in that it is operated continuously in a distillation column which is fed with the mixture resulting from the absorption of the propylene in the aqueous sulfuric acid and with said monocarboxylic acid, this column is heated to a temperature between 75 and 140ºC and maintained at atmospheric pressure or at an approximate pressure so that the formation reactions of the ester alone or of the ester and of isopropanol are developed in said column and so that the products formed are separated by distillation, of residual aqueous sulfuric acid.
