Paragraph 0019; 0020; 0024, (2018/12/05)
PROBLEM TO BE SOLVED: To provide a production method for obtaining (meth) acrylate in high yields, by preventing a large amount of waste from produced from by-products, like the conventional art. SOLUTION: A method for producing (meth) acrylate includes the reaction between a compound represented by the following formula (I) and an aryl alcohol. Preferably, the reaction occurs in the presence of a catalyst of at least one metal compound selected from first Group metal compounds and second Group metal compounds.

Paragraph 0035; 0037; 0039; 0043, (2018/11/24)
PROBLEM TO BE SOLVED: To provide a method for producing less discolored (meth)acrylic naphthyl ester at a high yield by reacting (meth)acrylic anhydride with naphthol, and to provide a method for producing (meth)acrylic naphthyl ester achieving high polymerization rate. SOLUTION: There is provided a method for producing (meth)acrylic naphthyl ester by reacting naphthol and (meth)acrylic anhydride, wherein, the production method of (meth)acrylic naphthyl ester is characterized in making a carbonate salt present in the reaction system of the naphthol and the (meth)acrylic anhydride.
