Study on the synthesis and properties of sulfate-spacered gemini surfactants
摘要
Abstract
Gemini surfactants,in which the two hydrophilic headgroups are linked by a spacer nearby,have unique properties that arise from their particular molecular structure.The spacer group therein is important and indispensable in the molecular structure of gemini surfactants.A large number of studies so far have been devoted to the effects of different spacers,but sulfate-containing spacers are rarely reported.In this work,a series of sulfate-spacered gemini surfactants with different degrees of sulfonation(14-x SO4-14)were synthesized from 14-OH-14 by sulfonation using different amount of chlorosulfonic acid.The molecular structure was characterized using 1H NMR and electrospray ionization mass spectroscopy(ESI-MS),and the degree of sulfonation was measured using inductively coupled plasma-optical emission spectrometry(ICP-OES).The results showed that,compared with unsulfonated 14-OH-14,the cmc of 14-xSO4-14 gradually decreased with increasing degree of sulfonation,and a minimum was obtained at x=1.0(decreasing the cmc by one order of magnitude).Furthermore,14-x SO4-14 exhibited greater abilities to self-assemble and to reduce surface/interfacial tension.14-x SO4-14 could not only reduce the oil-water interfacial tension to an ultra-low level,but also maintain it for a wide time window.Among these geminis with different degrees of sulfonation,14-0.2SO4-14 exhibited the best foaming ability and foam stability and the best antimicrobial effect against E.coli,while 14-0.6SO4-14 had the best antimicrobial effect against S.aureus.关键词
