研究了以甲醇和叔丁醇为原料合成甲基叔丁基醚用催化剂及反应条件。实验表明:用稀盐酸浸渍处理的732型强酸性阳离子交换树脂具有良好的催化效果。反应的最佳条件为:甲醇与叔丁醇摩尔比1:1,催化剂用量24％,沸腾回流7 h,此时转化率为51.3％,产率可达37.2％。 The catalysts and reaction conditions for the synthesis of methyl tert-butyl ether using methanol and tert-butanol as raw materials were studied. Experiments show that: dilute hydrochloric acid impregnated 732 strong acid cation exchange resin has a good catalytic effect. The optimum conditions for the reaction were as follows: the molar ratio of methanol to t-butyl alcohol was 1: 1, the amount of catalyst was 24% and the boiling was refluxed for 7 h. At this time, the conversion was 51.3% and the yield was 37.2%.
