一般描述

价格包含了联邦税。
纯乙醇是一种非变性的2000proof乙醇。乙醇，一种伯醇，是合成各种化合物的重要原料。它可以通过糖蜜的发酵或乙烯的水合作用而合成。在氢氧化钠存在下，它在羰基化合物的转移氢化过程中可起到氢源和反应介质的作用。乙醇/水熏蒸对柴油发动机性能的影响已被研究。分光光度级的溶剂具有高纯度及低紫外吸收率。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Ethanol is environmentally preferable green solvent and thus it aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks". 

应用
