CaX-Mg(ClO₄)₂ molecular sieve has been obtained from CaX in the presence of 20% Mg(ClO₄)₂ in mcrowave over of 650 W for 20 min. The product contains 17% Mg(ClO₄)₂ and has been characterized by XRD, IR, Hammett and BET measurements. The acid content of CaX-Mg(ClO₄)₂ increased obviously in comparison with CaX. When octanol was heated with equal mol of ethylene epoxide(EO) at 100℃ for 2 h using CaX-Mg(ClO₄)₂ catalyst,the conversion of alcohol was 77% and the concentration of (EO)₁ and (EO)₂ was 78%.
