Ethyl esters of unsaturated monocarboxylic acids of 1-4 C atoms are prepared by absorbing ethylene on an ethylsulphuric ester and subjecting the product to acidolysis with an unsaturated monocarboxylic acid of 1-4 C atoms, the ethylene : sulphuric acid molar ratio in the acidolysis being not below 1: 1. The unsaturated acid used is, for example, acrylic acid.
