PROBLEM TO BE SOLVED: To produce a high-purity polyfunctional (meth) acrylate at a high conversion using an inexpensive solid catalyst that can be easily separated from a product at the end of a reaction. Further, the present invention provides a method for producing a polyfunctional (meth) acrylate by effectively preventing the polymerization of the (meth) acrylate. SOLUTION: As a catalyst, one or more of calcium oxide, calcium hydroxide, magnesium oxide or magnesium hydroxide and sodium or potassium hydroxide, halide, carbonate, hydrogen carbonate, carboxylate or alkoxide are used. Using any one or more, A method for producing a polyfunctional (meth) acrylate by a transesterification reaction between a (meth) acrylate and a C2-20 polyhydric alcohol. |
