摘要/Abstract

摘要：

壬基酚聚氧乙烯醚-10（NPEO₁₀）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（NPEO_n）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NPEO₁₀的应用性能,以期在NCEO_n的构效关系方面,为提供NPEO₁₀的环境友好型替代品提供理论依据。实验结果表明,NCEO₇具有与NPEO₁₀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NPEO₁₀略好的乳化能力,有望替代NPEO₁₀作为乳化剂应用于农药、制药和石油等领域中。

Abstract:

The substitution of nonylphenol polyoxyethylene ether-10（NPEO₁₀）is a subject regarding environmental and regulatory requirements. Nonylcyclohexanol polyoxyethylene ether（NCEO_n）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 NCEO_n and NPEO₁₀were 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 NCEO_n. 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.

Key words: nonionic surfactant, nonylcyclohexanol polyoxyethylene ether, surface property, emulsifying property
