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.
通式(II)的高纯度环脂族二环氧化合物是通式(I)的环脂族二烯烃化合物的环氧化产物,其气相色谱法(GC)检测到的异构体含量不超过 15%:
其中 X 代表选自例如 O、S、-SO-、-SO2-、-CH2- 和-C(CH3)2- 所组成的组的二价基团;R1 至 R18 可以彼此相同或不同,并且各自代表氢原子、卤素原子、可能含有氧原子或卤素原子的烃基或可能被取代的烷氧基。这种高纯度环脂族二环氧化合物的制备方法是:通过蒸馏生产环脂族二烯烃化合物,用基本上不含水的脂肪族过羧酸环氧化该化合物,进行脱溶剂,并通过蒸馏进一步纯化环氧化化合物。
