烷基乙二胺三乙酸衍生物的制备与表征

Preparation and Characterization of Derivatives of Ethylenediamine Triacetate Acid

以氯乙酸和烷基乙二胺为反应物,在特定条件下合成一种新型的具有亲油性和络合基团的螯合型表面改性剂烷基乙二胺三乙酸衍生物(烷基ED3A)。研究反应条件对合成产物的影响,结果表明:合成烷基乙二胺三乙酸衍生物(烷基ED3A)的较佳反应条件是反应时间10 h,反应物氯乙酸为0.6 mol;产品烷基乙二胺三乙酸衍生物具有良好的亲油性。

The derivatives of ethylenediamine triacetate acid（ SED3A）,which had pro- oil groups and chelating groups,was prepared by chloroacetic acid and alkyl ethylenediamine under specific condition. Effects of reaction conditions on product were studied. Results showed that the preferred condition of preparing SED3 A was as follows： the reaction time was 10 h and the content of chloroacetic acid was 0. 6 mol,SED3 A had good lipophilicity.
