General description

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。
价格包含了联邦税。
我们竭诚为您带来绿色替代产品,以确保符合一项或多项绿色化学12项原则要求。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。 

Application

纯乙醇(乙醇)已用于制备:
  • 乙醇溶液用于合成Ga-68 DOTATATE【DOTA -(Tyr3)- octreotate(其中DOTA= 1,4,7,10-四氮杂环-十二烷-1,4,7,10-四乙酸)】,采用自动合成系统。
  • 马兜铃酸储备溶液用于分光光度分析。
  • 纳米壳的二氧化硅颗粒核心,采用改良Stöber法。
  • 与水结合的聚乙烯吡咯烷酮(PVP)溶液,采用溶液(空气)吹制法合成PVP超细纤维。

Packaging

溶剂用M瓶(M-Bottle for Solvents)
作为实验室试剂的全球领导者,我们始终如一地不断探索提高产品安全性的新方法。新开发4L溶剂瓶采用先进的密封技术消除漏液,让溶剂处理变得更加安全和便利。
