摘要： An alicyclic diepoxy compound (A) represented by formula (I) is produced in high purity and high yield at low cost, by epoxidizing the corresponding alicyclic diolefin compound with an organic percarboxylic acid. The curable epoxy resin composition has high reactivity for various curing agents, low viscosity, and excellent workability. A cured product thereof shows useful physical properties for uses in coatings, inks, adhesives, sealants, and encapsulants, etc. It is of extremely high quality as an epoxy resin composition for the encapsulation of electronic parts. A stabilizer for an electrical insulating oil (the alicyclic diepoxy compound or an electrical insulting oil containing the compound) is low in acid value, and the stabilizer improves the properties of the insulating oil. A cured product obtained by curing a casting epoxy resin composition for electrical insulation has excellent properties such as high bending strength, high Tg, and low permittivity.

摘要： Disclosed is a method for producing a cyclic olefin compound having two or more cyclohexene rings per molecule via intramolecular dehydration of an alicyclic alcohol having two or more hydroxylated cyclohexane rings per molecule. The method includes the step (i) of heating the alicyclic alcohol at a temperature of 130° C. to 230° C. and a pressure greater than 20 Torr in an organic solvent in the presence of a dehydration catalyst, to carry out dehydration of the alicyclic alcohol while distilling off by-product water, which dehydration catalyst is liquid or soluble in a liquid reaction mixture under the reaction conditions; and the subsequent step (ii) of heating the resulting reaction mixture at a temperature of 50° C. to 220° C. and a pressure of 200 Torr or less to recover the cyclic olefin compound as a distillate. According to the method, side reactions such as isomerization are suppressed, and high-purity cyclic olefin compounds with less impurities can be simply and efficiently obtained in high yields.
