摘要： The present invention discloses a composition comprising at least one or more stereoisomers of a compound represented by the following Formula (1), wherein, in a gas chromatogram obtained by analyzing the composition by gas chromatography, the ratio of the area of the maximum peak with respect to the total area of peaks derived from the stereoisomers is 90% or more. The present invention also discloses: a curable composition comprising the above described composition, and one selected from the group consisting of a thermal cationic polymerization initiator, an acid anhydride-based curing agent and a curing accelerator, and a photo-cationic polymerization initiator; as well as a cured product therefrom. The above described curable composition is useful in that it allows for the production of a cured product having a high heat resistance. (In the Formula (1), R1 to R18 are each independently selected from the group consisting of a hydrogen atom, an alkyl group and an alkoxy group.)

摘要： A high-purity cycloaliphatic diepoxy compound of General Formula (II) is an epoxidized product of a cycloaliphatic diolefinic compound of General Formula (I) having an isomer content as detected in gas chromatography (GC) of 15% or less: wherein X represents a bivalent group selected from the group consisting of, for example, O, S, —SO—, —SO2—, —CH2—, and —C(CH3)2—; and R1 to R18 may be the same as or different from each other and each represent hydrogen atom, a halogen atom, a hydrocarbon group which may contain oxygen atom or a halogen atom, or an alkoxy group which may be substituted. Such a high-purity cycloaliphatic diepoxy compound is prepared by producing the cycloaliphatic diolefinic compound through distillation, epoxidizing the compound with an aliphatic percarboxylic acid containing substantially no water, carrying out desolvation, and further purifying the epoxidized compound through distillation.
