    摘要: An object of the invention is to provide a method for producing a (meth)acrylate ester compound by the transesterification of an alkyl (meth) acrylate with an alcohol compound having a tertiary hydroxyl group so as to esterify all the hydroxyl groups present in the alcohol compound with a high yield or, in a preferred embodiment, a method for esterifying a polyhydric alcohol compound having a tertiary hydroxyl group and also having a primary hydroxyl group and/or a secondary hydroxyl group by one-pot transesterification into a (meth)acrylate ester compound of the polyhydric alcohol. The method for producing a (meth) acrylate ester compound includes a step (I) of transesterifying an alkyl (meth)acrylate with an alcohol compound having a tertiary hydroxyl group using a transesterification catalyst including a complex of iron with a specific ligand, the water content in the transesterification reaction system being not more than 1000 ppm.
