聚乙二醇单甲醚溴代衍生物的合成研究

Study on synthesis bromination derivatives of polyethylene glycol monomethyl ether

本文以三溴化磷为溴化剂与聚乙二醇单甲醚反应合成其溴代衍生物,通过测定反应前后样品羟值的方法计算反应的转化率,从而确定了较佳的反应条件,并用红外光谱分析及化学分析法等手段对产物的结构进行了分析论证。

Novel brominated derivatives were obtained by the systhesis of polyethylene glycol monomethyl ether with phosphorus tribromide. The yield was calculated by determining the hydroxyl value, and the reacting conditions were determined. The structures of the adducts were proved with the aid of IR spectrum and chemical analysis .
