【摘要】 报道了在ＺＷ 固体酸催化剂上甲醇和环氧乙烷的醚化反应。结果表明，ＺＷ 固体酸具有很高的催化活性和较窄的相对分子质量分布。采用间歇釜式反应器，在甲醇∶环氧乙烷＝ １０∶１（ 摩尔比） 、催化剂的用量为甲醇质量的１ ％～５ ％ 、反应温度６５ ～７５ ℃、操作压力＜ ０－３ ＭＰａ 的条件下，环氧乙烷的转化率为１００ ％ 、乙二醇单甲醚的选择性高于９３ ％ 。确立了最佳工艺参数并成功地进行了工业放大。更多还原

【Abstract】 Etherification of methanol with ethylene oxide by ZW solid acid catalyst is reported.The results obtained show that the catalyst possesses higher catalytic activity and narrow product distribution.Besides,it is an environmentally friendly catalyst.Suitable reaction conditions in a batch reactor are as follows:MeOH/EO=10/1 (molar ratio);ZW catalyst,1%～5% of methanol;reaction temperature 66～75 ℃;operational pressure<0 3 MPa.Under these counditions,the conversion of EO is 100%;selectivity of 2-methoxyethanol with respect to the products is over 93%;byproducts (double ether etc.)0 1%.The best parameters are obtained.更多还原
