Abstract: Method for the production of monoethylenically unsaturated carboxylic esters, in which, after the esterification is complete, a) the product mixture is extracted in a first extraction stage at a temperature of 10 to 40 DEG C with 5 to 30% by volume, based on the product mixture, of water and b) in a second extraction stage at a temperature of 10 to 30 DEG C the aqueous phase from the first extraction stage is extracted with one to four times the amount by weight of alkanol to be esterified.
