A liquid trifunctional epoxy compound with a total chlorine content of 100 ppm or less represented by general formula (1) is obtained by epoxidizing a triallyl ether represented by general formula (2) with a peroxide and the liquid epoxy compound is useful as a diluent in a variety of applications, particularly useful as a liquid encapsulating material in electronic applications: R[-(OCH2CH2)n-OG]3 (1) R[-(OCH2CH2)n-O-CH2-CH=CH2]3 (2) (wherein R is a trivalent hydrocarbon group in which 3 different carbon atoms participate in bond formation or, more particularly, a straight-chain or branched hydrocarbon group containing 3-10 carbon atoms, a cycloalkane group containing 6 carbon atoms or a hydrocarbon group containing 7-20 carbon atoms and consisting of hydrocarbon chains and cycloalkane rings, n is 0, 1, or 2 and G is glycidyl group).
