Abstract

Alkyl esters of aliphatic carboxylic acids are prepared by absorbing an olefine in concentrated sulphuric acid under elevated pressure, reacting with mono-chloroacetic acid, separating the alkyl monochloroacetate by distillation, reacting the separated product with an aliphatic carboxylic acid (other than monochloroacetic acid) in the presence of concentrated sulphuric acid, and separating the resultant alkyl ester of the aliphatic carboxylic acid by distillation. The sulphuric acid from the first distillation stage may be recycled, and the excess carboxylic acid recovered in the final separation may also be recycled. Straight or branched chain olefines, e.g. ethylene, propylene and butene-1, may be used. An example describes the preparation of ethyl acetate from ethylene and acetic acid and detailed apparatus is also described.
