ABSTRACT:
A process for producing an acrylic acid ester or a methacrylic acid ester having a benzoic acid group from a benzoic acid derivative having a hydroxyalkyl group in the presence of an acid catalyst without using an azeotropic solvent with water having a strong toxicity and also without using acrylic acid chloride which has a strong tearing property, is hard to be handled and generates a by-product in the reaction. In the above process, the solvent for the benzoic acid derivative consists essentially of (meth)acrylic acid.
