    Abstract: Alkyl esters of alpha , beta -monoolefinically unsaturated monocarboxylic acids are prepared by esterifying the monocarboxylic acid with an alcohol of 6 to 20 carbon atoms in the presence of from 0.1 to 5% by weight, based on the reaction mixture, of a strong acid and in the presence of a polymerization inhibitor and an oxygen-containing gas, at from 80 DEG to 150 DEG C., by a process in which the molar ratio of the monocarboxylic acid to the alcohol is from 1:0.8 to 1:1.2, and the water of reaction is separated off from the reaction mixture while passing an inert gas containing from 1 to 20% by volume of oxygen through the reaction mixture.
