PROBLEM TO BE SOLVED: To provide a method for producing a (meth)acrylate from an alkylene oxide adduct of a glycerol-based compound, reducing the production of a polymer as a by-product in a dehydrating esterification process as less as possible, enabling a safe operation improved with its productivity and maintaining a good color tone of the obtained (meth)acrylate so as to be able not to damage the added value as a merchandize. SOLUTION: This method for producing the (meth)acrylate is provided by performing the dehydrating esterification of the alkylene oxide adduct of glycerol or diglycerol with a (meth)acrylic acid in the presence of an acid catalyst and a polymerization inhibitor consisting of a copper compound and a phenol-based compound. As the copper compound, a cuprous halide is preferable, and as the phenol-based compound, hydroquinone or hydroquinone monomethyl ether is preferable. COPYRIGHT: (C)2007,JPO&INPIT
