摘要： The present invention provides a method of recovering a (meth)acrylic acid ester, which comprises the steps of: (a) carrying out an esterification reaction between an alcohol and (meth)acrylic acid in the presence of a catalyst to obtain a (meth)acrylic acid ester, wherein a byproduct is generated together with the (meth)acrylic acid ester; and (b) subjecting the byproduct generated in step (a) to a reaction with a catalyst and water in a reactor, wherein the water is fed into the reactor in order that water content exceeds 0 wt % but is 10 wt % or less in the reactor based on the total weight of reactants comprising the byproduct, the catalyst and the water, and thereby separating the (meth)acrylic acid, the alcohol and the (meth)acrylic acid ester contained in the byproduct from the byproduct to obtain the (meth)acrylic acid, the alcohol and the (meth)acrylic acid ester as a recovered product.
