Abstract: An acrylic compound is represented by Formula 1. In Formula 1, R1 and R2 are each independently a C2 to C10 alkylene group, a C6 to C20 arylene group, a C7 to C20 alkylarylene group, or a C7 to C20 arylalkylene group. Ar1 is a C6 to C10 aryl group. X1 and X2 are each independently —O— or —S—. Y1 and Y2 are each independently a hydrogen atom, —OH, —SH, —NH2, and at least one of Y1 and Y2 is n1, n2, n3 and n4 are each independently 1 to 4 on average. The acrylic compound includes no halogen atoms and has a high refractive index of about 1.65 or greater.

Abstract: The present invention relates to a production method of ?-methylene lactone which comprises the following steps: (A) a step of producing an enolate intermediate by making lactone react with alkyl formate under the presence of an alkoxide base; and (B) making the enolate intermediate react with paraformaldehyde. The production method of the present invention is capable of reducing the process time, improving yield, and minimizing the contamination of a reactor.
