壬基环己醇聚氧乙烯醚表面活性剂的性能研究

Study of the properties of nonylcyclohexanol polyoxyethylene ether

壬基酚聚氧乙烯醚-10(NPEO_(10))的替代是一个顺应环境和法规的需求问题,而壬基环己醇聚氧乙烯醚(NCEO_n)的结构与壬基酚聚氧乙烯醚(NPEOn)高度相似,原料来源一致,有可能作为其替代品。系统考察和比较了NCEO_n和NPEO_(10)的应用性能,以期在NCEO_n的构效关系方面,为提供NPEO_(10)的环境友好型替代品提供理论依据。实验结果表明,NCEO_7具有与NPEO_(10)最为接近的乳化和润湿性能,且对橄榄油、液体石蜡和二甲基硅油具有较NPEO_(10)略好的乳化能力,有望替代NPEO_(10)作为乳化剂应用于农药、制药和石油等领域中。

The substitution of nonylphenol polyoxyethylene ether-10(NPEO10)is a subject regarding environmental and regulatory requirements.Nonylcyclohexanol polyoxyethylene ether(NCEOn)possesses a structure similar to nonylphenol polyoxyethylene ether,with the same source of raw materials,and is most likely to be used as a substitute.The application performances of NCEOn and NPEO10 were systematically examined and compared,in order to provide a theoretical reference for seeking environmentally friendly alternatives to NPEO10 in terms of the structure-activity relationship of NCEOn.The experimental results show that NCEO7 is the one most like NPEO10 in emulsifying and wetting properties,and it is slightly better than NPEO10 in emulsifying olive oil,liquid paraffin and dimethicone.Therefore,NCEO7 can be a candidate for substituting NPEO10 as an emulsifier in industrial fields such as pesticides,pharmaceuticals and petroleum.
