Abstract: Provided are a stereoisomer of an epoxy compound that when contained in a curable composition, can improve the heat resistance and dielectric properties of the cured product of the curable composition, a curable composition containing the stereoisomer, and a cured product of the curable composition. A stereoisomer of an epoxy compound represented by Formula (1) below, the stereoisomer being represented by Formula (2), and a curable composition containing the stereoisomer are used:




in which in Formula (1), R1 to R18 are each independently selected from the group consisting of hydrogen, an alkyl group, and an alkoxy group; and




in which in Formula (2), R1 to R18 are each the same as in Formula (1).

Abstract: The present invention provides an alicyclic epoxy acrylate compound that can have high heat resistance in the form of a cured product when contained in a curable composition, a curable composition, and a cured product.
An alicyclic epoxy acrylate compound represented by the following Formula (1) where A denotes an oxygen atom and a curable composition comprising thereof are used: wherein one of R1 and R2 is a (meth)acryloyloxy group, the other of R1 and R2 is a hydrogen atom, R3 to R20 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, and an alkoxy group, and A is an oxygen atom or A is not present, and a carbon atom to which R8 binds and a carbon atom to which R9 binds together form a double bond.

Abstract: The invention provides a method for producing an epoxy compound by hydrogen peroxide using an organic compound having a carbon-carbon double bond as a raw material, wherein a by-product is suppressed from being generated and the epoxy compound is produced in a high yield. In particular, the invention provides a method for producing an epoxy compound involving oxidizing a carbon-carbon double bond in an organic compound with hydrogen peroxide in the presence of a catalyst, wherein the catalyst comprises a tungsten compound; a phosphoric acid, a phosphonic acid or salts thereof; and an onium salt having an alkyl sulfate ion represented by formula (I) as an anion: wherein R1 is a linear or branched aliphatic hydrocarbon group having 1 to 18 carbons, which may be substituted with 1 to 3 phenyl groups.
