METHOD FOR PRODUCING POLYFUNCTIONAL (METH) ACRYLIC ACID ESTER

The present invention provideS a method for producing a polyfunctional (meth)acrylic acid ester, which enables the final product to contain no aromatic hydrocarbon compound by not using an aromatic hydrocarbon compound, the environmental impact of which has been problematic, as an organic solvent. The present invention discloses a method for producing a polyfunctional (meth)acrylic acid ester by causing an esterification reaction of a (meth)acrylic acid and a polyhydric alcohol in the presence of an acid catalyst. In this method, the esterification reaction is carried out using, as a reaction solvent, an aliphatic hydrocarbon compound and/or alicyclic hydrocarbon compound having 6-12 carbon atoms and a boiling point of 160 DEG C or less at atmospheric pressure and neutralization and water washing of the thus-obtained reaction liquid is carried out using, as an organic solvent, a ketone compound and/or an ester compound, so that a polyfunctional (meth)acrylic acid ester which does not contain an aromatic hydrocarbon compound is produced.
