(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).
一种总氯含量为100 ppm或更少的液态三官能团环氧化合物,由通式(1)表示,通过用过氧化物对通式(2)表示的三烯基醚进行环氧化反应而得到,该液态环氧化合物可用作各种应用中的稀释剂,尤其是在电子应用中作为液体封装材料特别有用:R-[(OCH2CH2)n]-OG3(1),R-[(OCH2CH2)n]-O-CH2-CH(CH3)2 3(2)(其中,R是三价的碳氢基团,其中3个不同的碳原子参与键形成,或更具体地说,是含有3-10个碳原子的直链或支链碳氢基团,含有6个碳原子的环烷基团或含有7-20个碳原子的碳氢基团,由碳氢链和环烷环组成,n为0,1或2,G是环氧丙基基团)。
