聚氧乙烯脂肪醇的合成与结构的分析方法

Methods of synthesis and structure analysis of polyoxyethylene aliphatic alcohols

聚氧乙烯脂肪醇是由脂肪醇和环氧乙烷进行加成反应得到的。聚氧乙烯脂肪醇的分析方法包括化学分析,物化测试以及光谱分析。采用核磁共振(NMR)可以确定聚氧乙烯脂肪醇中的烷基值(R 值)和聚氧乙烯链的聚合度(n 值),并能计算出平均分子量。这些分析方法对指导生产和应用以及对未知非离子表面活性剂的剖析具有重要作用。

Methods of synthesis and structure analysis ofpolyoxyethylene aliphatic alcohols are described.Polyoxyethylene aliphatic alcohols are producedby the addition reaction of aliphatic alcohols andethylene oxide(EO).Analytical methods for struc-ture determination of polyoxyethylene aliphaticalcohols include chemical analysis,physical-chem-ical methods and spectra analysis.Molecularweight,R and n values of polyoxyethylenealiphatic alcohols can be determined by NMRmethod.These methods play an important rolein the production.application and determinationof structure of unknown non-tonic surfactants.
