摘要
为了开发具有清凉香气的薄荷醇类烟用香料,用甲苯作溶剂,对甲苯磺酸作催化剂,在l-薄荷醇与d-酒石酸摩尔比为2.4:1的条件下回流反应合成d-酒石酸-l-薄荷醇双酯,并通过分子蒸馏在80℃和1Pa的条件下分离纯化,获得含量为97.4%的酒石酸薄荷双酯,总收率达80%。对合成产物进行了卷烟加香试验,评吸结果表明,在烟丝中添加0.001%的d-酒石酸-l-薄荷醇双酯能赋予卷烟清凉感,并柔和烟气。
In order to develop a menthol flavor for cigarette, l-menthyl d-bitartrate was synthesized by refluxing d-tartaric acid and l-menthol in mol ratio of 2.4：1 with toluene as solvent and p-toluene sulfonic acid as catalyst. The synthetic was purified by molecular distillation at 80℃ and 1 Pa, a product contained 97.4% of l-menthyl d-bitartrate was obtained, and the yield was up to 80%. The panel test results of cigarette favored with the synthetic at a ratio of 0. 001% showed that the smoke was milder and offered a fresh and cool taste.
