The present invention, (meth) by an ester exchange reaction between alkyl acrylate and an alcohol compound having a tertiary hydroxyl group and allowed esterification in a high yield with all the hydroxyl groups contained in the alcohol compound (meth) acrylic acid ester compound the method of manufacturing preferably have a tertiary hydroxyl group, and, from a polyhydric alcohol compound having a primary hydroxyl group and / or secondary hydroxyl groups, 1 pot of polyhydric alcohol (meth) acrylic acid ester compound and to provide a process for producing.
The alcohol compound having a tertiary hydroxyl group, the specific ligand using a transesterification catalyst comprising a complex of iron is coordinated, with a (meth) step of performing alkyl acrylate ester exchange reaction (I) (meth) manufacturing method of a manufacturing method of an acrylic acid ester compound, wherein the water content in the transesterification reaction system is 1000ppm or less (meth) acrylic acid ester compound.
