对烷-3-醇分子式：C10H20O分子量：156.26CAS号：2216-51-5性质：无色针状结晶或粒状。熔点41-43℃（42-45℃），沸点216.5℃，相对密度0.890（15/15℃），折光率1.458。易溶于醇、氯仿、醚、冰醋酸、液状石蜡及石油醚，微溶于水。薄荷醇含有三个不对称碳原子，已知四个空间顺式和反式异构体，它们每个都有右旋型、左旋型以及消旋型。左旋薄荷醇具有特征有薄荷香气并有清凉的作用。消旋薄荷醇（[89-78-1]）也有清凉作用，其它的异构体无清凉作用。制备方法：薄荷醇可由天然薄荷原油提纯也可用合成法制取。唇形科植物薄荷的地上部分（茎、枝、叶和花序）经水蒸气蒸馏所得的精油称薄荷原油，得油率为0.5-0.6。合成薄合脑的方法有多种。1.从香茅醛中制造 利用香茅醛易环化成异胡薄荷醇的性质，将右旋香茅醛用酸催化剂（如硅胶）环化成左旋异胡薄荷醇，分出左旋异胡薄荷醇，氢化生成左旋薄荷。其立体导师构体经热裂解可部分地遭到转变成右旋香茅醛，再循环使用。2.从百里酚中制造 在间甲酚铝存在，对间甲酚进行烷基化反应生成百里酚。经催化加氢得所有四对薄荷醇立体异构体（即消旋薄荷醇、消旋新薄荷醇、消旋异薄荷醇和消旋新异薄荷醇）。将其进行蒸馏，取消旋薄荷醇馏分，制造酯后反复重结晶，进行异构体的分离和光学拆分。分离出来的左旋薄荷醇酯，经皂化后得薄荷脑。用途：薄荷脑和消旋薄荷脑均可用作牙膏、香水、饮料和糖果等的赋香剂。在医药上用作刺激药，作用于皮肤或粘膜，有清凉止痒作用；内服可作为驱风药，用于头痛及鼻、咽、喉炎症等。其酯用于香料和药物。在世界上，我国和巴西是主要的天然薄荷生产国，薄荷油的年产量均达到2000-3000t。
