摘 要:以脱氢枞酸、丙烯海松酸、马来海松酸为原料分别与2,3-环氧丙基三甲基氯化铵反应,得到单、双、三季铵盐Ⅰ、Ⅱ及Ⅲ3种松香酯羟丙基季铵盐表面活性剂。采用IR,1H NMR,13C NMR对产物结构进行了表征,并对产物的临界胶束浓度(Ccmc)、表面张力(γcmc)、乳化性能、泡沫性能及抑菌性能进行了研究。结果表明,3种松香酯羟丙基季铵盐表面活性剂的Ccmc值分别为3.58×10-4、2.53×10-4和3.25×10-4mol/L,对应的γcmc分别为38.9、28.9、33.5 m N/m;乳化时间分别为31、33、38 min;表面活性剂Ⅰ的起泡性较好,起泡高度达到115 mm、5 min后泡沫高度为85 mm;随着季铵盐数量的增加,亲水亲油平衡值(HLB)增大,表面活性剂的亲水性增强;季铵盐Ⅰ对金黄色葡萄球菌具有良好的抑制活性,最小抑菌浓度为4 mg/L,抑菌效果优于市售的新洁尔灭,与氨苄青霉素钠相当。Three rosin ester hydroxlpropoyl quaternary ammonium surfactants (Ⅰ, Ⅱ and Ⅲ) , were synthesized from dehydroabietic acid, acrylopimaric acid, maleopimaric acid and 2, 3-epoxy propyl trimethyl ammonium chloride (GTMAC). Their structures were characterized by IR, 1H NMR and 13C NMR spectra, respectively. The critical micelle concentration (Ccmc), surface tension (γcmc), emulsifying ability, foaming ability and bactericidal activity of three quaternary ammonium surfactants were evaluated. The results showed that their Ccmc values are 3. 58 × 10^-4 , 2. 53 × 10^-4 and 3. 25 × 10^-4 mol/L, theirγcmc were 38. 9, 28. 9 and 33. 5 mN/m, their emulsifying abilities were 31, 33 and 38 min, respectively. The foaming ability ofⅠ was better than the others, foaming ability was 115 mm, and 85 mm after 5 min. With the increase in the number of quaternary ammonium salt, HLB value was increased, and the hydrophilic of surfactant was enhanced. Compound Ⅰexhibited excellent antibacterial activity against Staphyloccocus aureus, and the minimum inhibition concentration was 4 mg/L.
