一般描述

甲醇HCl(溶于甲醇中的氯化氢)特别适用于制备挥发性(短链)脂肪酸的甲酯。通过在酸性催化剂(例如HCl)存在下,在密封容器中、高温下将其与无水乙醇(例如甲醇)一起进行短暂加热,可实现脂肪酸的酯化。在反应中,一个脂肪酸分子和一个醇分子通过释放一个水分子而发生连接。衍生物可以从反应介质中快速且容易地进行定量回收。

应用

更多信息请参见产品信息
适用于皮质类固醇、雌激素、脂肪酸、啤酒花和啤酒苦味酸、脂类、甲酸和乙酸(香烟烟雾中)的衍生化。

特点和优势

  • 脂肪酸的衍生化,特别是挥发性(短链)脂肪酸
  • 与挥发性副产物发生清洁反应(无副反应)
  • 提供清洁、快速、定量的衍生化
