Abstract:
1. A process for preparing a high-purity cycloaliphatic diepoxy compound represented by the following Formula (II), the process comprising the steps of: purifying a cycloaliphatic diolefinic compound represented by the following Formula (I) through distillation; epoxidizing the purified cycloaliphatic diolefinic compound with an aliphatic percarboxylic acid containing substantially no water; carrying out desolvation of the epoxidized compound, and further secondarily purifying the epoxidized compound through distillation: wherein X represents a bivalent group selected from the group consisting of an oxygen atom, sulfur atom, —SO—, —SO 2 —, —CH 2 —, —C(CH 3 ) 2 —, —CBr 2 —, —C(CBr 3 ) 2 —, and —C(CF 3 ) 2 —; and R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 , R 13 , R 14 , R 15 , R 16 , R 17 , and R 18 may be the same as or different from each other and each represents a 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.
