摘　　要：以环氧乙烷加成数接近9的烷基醇聚氧乙烯醚为研究对象,比较性研究了壬基环己醇聚氧乙烯醚(9)、壬基酚聚氧乙烯醚(10)、异构十三醇聚氧乙烯醚(9)、仲醇聚氧乙烯醚(9)以及十二醇聚氧乙烯醚(9)五种非离子表面活性剂对几种日用化学品用油及其混合物的乳化力。实验结果表明,支链化疏水基更有利于非离子表面活性剂对油的乳化,壬基环己醇聚氧乙烯醚(9)具备替代壬基酚聚氧乙烯醚(10)在日用化学品中应用的潜力。This experiment studied 5 nonionic surfactants, the polyoxyethylene ethers that possess 9 or 10 oxyethylene ether units,that is, nonylcyclohexanol polyoxyethylene ether(9), nonylphenol polyoxyethylene ether(10), isomeric alcohol ethers(9), secondary alcohol polyoxyethylene ether(9) and dodecylpolyoxyethylene ether(9) on their emulsifying ability towards several household chemical oils and their mixtures. The experimental results show that branched hydrophobic group is more conducive to the emulsification, and nonylcyclohexanol polyoxyethylene ether(9) has the potential to be used in daily chemicals as the alternative of nonylphenol polyoxyethylene ether(10).
