摘要
以薄荷脑为起始原料,先与环氧氯丙烷在无水三氯化铝催化作用下,反应制得1-氯-3-薄荷氧基-2-丙醇,然后经酯化、水解反应获得凉味剂薄荷甘油醚.三步反应总得率为71.3%,产品经色质分析证明其结构与薄荷甘油醚相符.该合成方法原料价廉易得、反应得率高、适合工业化生产.
L-Methyl glyceryl ether was synthesized from L-menthol and Epichlorohydrin by three steps. The total yield was 71.3%. The structure of Menthol glyceryl ether obtained was confirmed by GC-MS. This synthetic method had some advantages, such as cheap raw material and high yield, which is suitable for commercial production.
