摘要

通过两步反应，合成了三种磺酸钠型Gemini表面活性剂6， 6’-（丙基-1， 3-二基双氧）双（3-壬基苯磺酸钠）（9B-3-9B）、6， 6’-（正丁基-1， 4-二基双氧）双（3-壬基苯磺酸钠）（9B-4-9B）和6， 6’-（正戊基-1， 5-二基双氧）双（3-壬基苯磺酸钠）（9B-5-9B），并讨论了反应温度和反应时间对产物产率的影响，优化了反应条件。利用傅里叶变换红外光谱仪（FTIR）、核磁共振仪（1H NMR）和元素分析仪表征产物结构，并通过DCTA21表面界面张力仪测定其在水溶液中的表面张力。结果表明：与传统表面活性剂十二烷基苯磺酸钠（SDBS）相比，Gemini表面活性剂9B-m-9B（m=3， 4， 5）具有更高的表面活性，其临界胶束浓度（CMC）分别为0.14、0.11、0.12 mmol·L-1，对应的表面张力gCMC分别为29.43、29.26、28.22 mN·m-1。

Abstract

Three sulfonate sodium-containing Gemini surfactants

6'-(propane-1

3-diylbis(oxy)) bis(3-nonenzenesulfonate sodium) (9B-3-9B)

6'-(butane-1

4-diylbis(oxy)) bis(3-nonylbenzenesulfonic sodium) (9B-4-9B) and 6

6'-(pentane-1

5-diylbis(oxy)) bis(3-nonylbenzenesulfonate sodium) (9B-5-9B)

were synthesized through two-step reaction using nonylphenol (NP)

3-dibromopropane

4-dibromobutane

5-dibromopentane and chloro sulfonic acid as main starting materials. The influence of reaction temperature and time on the yields of 9B-m-9B was studied. The structures of 9B-m-9B were characterized by FTIR

1H NMR and elemental analysis

and their abilities to lower water surface tension were also evaluated by surface tension measurement. The yields were 59.94%

65.27% and 53.91% for 9B-3-9B

9B-4-9B and 9B-5-9B

respectively

when the reaction condition was at 0℃ for 6 h. Three synthesized surfactants 9B-m-9B (m=3

5) showed surface properties superior to conventional monomeric surfactant sodium dodecylbenzene sulfonate (SDBS)

and their critical micelle concentrations (CMC) were 0.14

0.11 and 0.12 mmol·L-1

gCMC were 29.43

29.26 and 28.22 mN·m-1 for 9B-m-9B(m=3

respectively.
