新型Gemini阳离子表面活性剂的合成和性能(3)——在烷基链中引入易水解基团促进生物降解

Synthesis and Properties of Novel Gemini Cationic Surfactants (3) --Introducing Hydrolyzable Group in Hydrophobic Chain to Improve Biodegradability

概述了烷基链中含有酰胺基和酯基的Gemini阳离子表面活性剂的合成、表面活性和生物降解性。含有酰胺基的Gemini阳离子具有优良的表面活性 ,但几乎不能生物降解 ;而含有酯基的Gemini阳离子不仅具有优良的表面活性 。

The synthesis of new types of Gemini cationic surfactants with amide or ester groups in hydrophobic chain and their surface-active and biodegradation properties are reviewed. The Gemini cationic surfactants with amide group in hydrophobic chain possess excellent surface-active properties but show poor biodegradability; the ones with ester group, however, possess both excellent surface-active properties and good biodegradability.
