摘要 研究了几种典型表面活性剂(脂肪醇聚氧乙烯醚硫酸钠AE3S、脂肪醇聚氧乙烯醚AEO-9、烷基糖苷APG-1214、椰油酰胺丙基甜菜碱CAB、有机硅表面活性剂FC-7160)在纯水溶液和50%乙醇溶液中的泡沫性能。结果表明,只有有机硅表面活性剂可以在50%乙醇溶液里起泡。通过测定平衡表面张力发现只有有机硅表面活性剂可以降低50%乙醇溶液的表面张力,而在加入碳氢表面活性剂后,乙醇溶液的表面张力没有变化。 The foaming properties of several typical surfactants(sodium lauryl polyoxyethylene ether sulfate(AE3S),fatty alcohol ethoxylate(AEO-9),alkyl polyglycoside(APG-1214),cocamidopropyl betaine(CAB)and silicone surfactant(FC-7160))were studied in aqueous and 50%ethanol solution,respectively.The results show that only silicone surfactant can foam in 50%ethanol solution.By measuring the equilibrium surface tension,it can be found that only silicone surfactant can reduce the surface tension of 50%ethanol solution,but hydrocarbon surfactants can not.
