摘　　要：众所周知,氟利昂(CFCs)会导致平流层中臭氧的减少,加剧全球变暖。为此,许多研究团队都在致力于研究氟利昂的替代品。本文基于大豆油和菜子油制备两种生物表面活性剂,并将其分别应用于W/O和O/W型清洗剂配方。将上述生物表面活性剂与月桂醇、蓖麻油和油酸混合,研究了它们在4～60℃冷热循环的相变化,从而确定最佳的单相的形成参数。分析了生物表面活性剂的生物降解性能、清洗效率和在工业清洗过程中对基质材料(金属、聚合物)的腐蚀伤害。结果显示:大豆油甲酯(SME)在W/O和O/W配方中的生物降解度分别为94.66%和95.60%,在最佳清洗条件下对模型污染物的清洗效率分别为99%和97%;而菜籽油乙酯(CEE)在W/O和O/W配方中的生物降解度分别为94.43%和93.87%,对模型污染物的清洗效率分别为58%和15%。SME的W/O和O/W清洗剂配方、CEE的W/O和O/W清洗剂配方对生铁和聚氯乙烯的腐蚀伤害是最大的,最大腐蚀度分别为0.11/7.65、0.44/5.79、0.11/11.80、和0.12/2.84(rmg/cm^3)。SME的W/O清洗剂相较于传统工业清洗剂中所使用的三氯乙烯(TCE),可以在更短时间(<5min)内实现更高的清洗效率(99%),因此,有望在工业清洗中作为CFC的替代品使用。Chlorofluorocarbons （CFCs） are known to cause depletion of the stratospheric ozone layer and to contribute to global warn-ring. For this reason, many researchers are investigating ahematives to CFCs. In the present study, bio-surfactants incorporating two oils, soy bean and canola, were prepared, and bio-surfactants in water in oil （W/O） and oil in water （O/W） types were produced, respectively. The phase behaviors of the as-prepared lauryl alcohol, caster oil, and oleic acid bio-surfactants were investigated under temperatures ranging from 4℃ to 60 ℃ to find the optimal single phase. The bio-surfactants additionally were analyzed for biodegradability, cleaning efficiency, and degree of corrosion of several metals and plastics, taking into due consideration the industrial deaning process for chemical impurities. For removal of flux （i.e., abietic acid that constitutes most of rosin） from 25℃ to 60 ℃ temperature by sonication treatment, first, the biodegradability （%） of the four bio-suffactants, namely the W/O and O/W formulated soybean methyl ester （SME） and canola ethyl ester （CEE） types, were detemained to be 94.66%, 95.60%, 94.43%, and 93.87%, respectively. Second, the cleaning efficiencies of the four biosurfactants were 99%, 97%, 58%, and 15%, respectively, under the optimal deaning conditions. Third, the degrees of maximal corrosion of caster iron and polyvinyl chloride （PVC） by W/O SME, O/W SME, W/O CEE, and O/W CEE were recorded xs 0.11/7.65, 0.44/5.79, 0.11/11.80 and 0.12/2.84 Dmg/cm3, respectively. Compared with trichloroethylene （TCE）＇s cleaning perfomlance for oil-contaminated brae pads, the W/O SME bio-surfactant showed better （99%） deaning efficiency in 〈5 min. Conclusively, the W/O SME bio-surfactant was judged to be a proper CFC ahemative for application to industrial cleaning processes.
