摘要
测定了无机盐、单元及多元醇、有机酸及离子型表面活性剂对３种非离子表面活性剂十二烷基聚氧乙烯聚氧丙烯醚Ｃ１２Ｈ２５（ＥＯ）ｍ（ＰＯ）ｎＨ（ＬＳ３６，ｍ＝３，ｎ＝６；ＬＳ４５，ｍ＝４，ｎ＝５；ＬＳ５４，ｍ＝５，ｎ＝４）浊点的影响．
The effects of additives, such as salts, alcohol, carboxylic acid and ionic surfactant on the cloud ponit of nonionic surfactant dodecylpolyoxyethylene polyoxypropylene ether were studied in the paper. It was found that the change of CP value coursed by salts followed the Schott additivity regulation and was determined by the characteristic of salts(such as charge of ions) and surfactants(such as group numbers of oxyethylene and oxypropylene); the effects of organic substances on the CP value of nonionic surfactant varied if the additives have a different kind of hydrophilic head or carbon chain length; the formation of mixmicell could be the reason why ionic surfactants greatly increased the CP value of nonionic surfactant, but more detail studies were needed to find the regulation.
