一般描述

价格包括联邦税。
我们致力于为您带来更加绿色的替代产品，这些产品遵守一项或多项绿色化学12项原则。乙醇是一种绿色环保溶剂，符合“更安全的溶剂和助剂”以及“使用可再生原料”的原则。 
纯乙醇是一种非变性的190 proof乙醇。乙醇是一种伯醇，是合成各种化合物的重要原料。它可以通过发酵从糖蜜中合成或通过乙烯的水合作用合成。在氢氧化钠存在下，在羰基化合物的转移氢化过程中，它起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有研究。分光光度级溶剂时一种高纯度等级，其具有低紫外吸收。

应用


  • 采用化学电容传感器阵列监测和评估酒精发酵过程。: 研究中的乙醇不仅是一种产品，而且是监测发酵过程的分析工具。该研究工作阐明了传感器技术与化学分析的结合，突出了饮料行业监测和质量控制分析技术的进步（Oikonomou et al., 2014）。

  • 来自土耳其中北部Boyali Höyük的古代黑种草籽。: 这项历史研究使用乙醇进行古代植物遗骸的保护和分析，反映了分析化学在考古研究中的关键作用，提供了有关古代农业实践的见解（Salih et al., 2009）。
