Preparation method of phytol and intermediates thereof

The invention discloses a preparation method of phytol and intermediates thereof, which comprises the following steps: (1) carrying out esterification rearrangement reaction on isophytol and anhydrideunder the action of perchlorate to obtain phytol ester; and (2) carrying out transesterification on the phytol ester to obtain the phytol. According to the preparation method disclosed by the invention, the total molar yield of the phytol can be up to 88.1%, the generation of potassium acetate or sodium acetate waste solids caused by a potassium hydroxide or sodium hydroxide hydrolysis process isavoided by adopting an ester exchange process, three wastes are effectively controlled, and the method is green and environment-friendly. 本发明公开了一种植物醇及其中间体的制备方法，该植物醇的制备包括以下步骤：(1)异植物醇与酸酐在高氯酸盐的作用下发生酯化重排反应，得植物醇酯；(2)植物醇酯经酯交换反应得植物醇。本发明的制备方法植物醇总摩尔收率可高达88.1％，并且采用酯交换工艺避免了因氢氧化钾或氢氧化钠水解工艺带来的乙酸钾或乙酸钠废固的产生，三废有效控制，绿色环保。
