文献报道合成异菠基烷基醚(3)的路线有两条.一条是莰烯(1)和(或)三环烯(2)在酸性催化剂作用下与醇发生反应生成3;另一条是以异龙脑为原料,与氢化钠、硫酸二烷基酯反应生成3.前者生成3的选择性不高,且产率较低;而后者选择性虽然比较高,但产率仍不理想,且所用原料较多.本文首次报道以氢型丝光沸石为催化剂催化1和(或)2与 C_1—C_4醇发生烷氧基化反应,以比较高的选择性和较好的产率得到一系列相应的烷基化合物(3a—3g),
There are two routes to the synthesis of isobornyl alkyl ether (3), one is the reaction of camphene (1) and (or) tricyclene (2) with alcohol under the action of acidic catalyst to generate 3 and the other one is Isoborneol as raw material, with sodium hydride, dialkyl sulfate reaction 3 former 3 is not high selectivity, and the yield is low; while the latter the selectivity is relatively high, but the yield is still not ideal, And the raw materials used more.This paper reports for the first time hydrogen-type mordenite catalyst 1 and (or) 2 and C 1 -C 4 alcohol alkoxylation reaction with a relatively high selectivity and good yield obtained a series The corresponding alkyl compounds (3a-3g),
