The traditional methods to produce anhydrous ethanol were introduced briefly in this paper.

简要介绍了传统制取无水乙醇的方法,重点介绍了生物质吸附法制取无水乙醇的方法及国内外的进展情况,并对无水乙醇的制取方法进行了展望。

Due to the ability of the bivalent magnesium cation to form stable chelate complexes with carbonyl compounds,magnesium methylate for example is used as a selective carbonyl condensing agent. Three synthesis routes was proposed based on literatures and comprehensive comparison with other ways. First,Magnesium methylate is prepared by reacting magnesium metal with dry methanol.The magnesium salts of"higher"primary alcohols,i.e.alcohols with ≥ 2 carbon atoms,do not react directly with pure alcohols under normal conditions.In fact catalysts are required to set the reaction in motion and the preparation is performed under pressure at the higher temperatures.

一、直接合成法:本文将镁与无水甲醇直接反应制得甲醇镁;"更高级"的醇(比如C≥ 2的醇)在无催化剂的条件下无法直接和镁进行反应,本文以CCl4为催化剂将无水乙醇与镁直接反应制得乙醇镁,但是以原甲酸三乙酯为催化剂无水乙醇与镁无法反应;不论是以CCl4为催化剂还是以原甲酸三乙酯为催化剂,丙醇均无法与镁直接反应。
