烯丙醇聚氧烷基醚的浊点及影响因子

 烯丙醇聚氧烷基醚(AAP)是一种非离子表面活性剂。通过实验测定了AAP的浊点，考察了分别添加非离子表面活性剂聚乙二醇（PEG）、离子表面活性剂十二烷基苯磺酸钠(LAS)、极性溶剂醇以及LAS和醇的混合物后，AAP浊点的变化。结果表明，PEG的加入基本不影响AAP的浊点；LAS或LAS与乙醇混合物的加入可改变AAP的浊点。随着LAS、LAS-乙醇混合物的加入，AAP的浊点大幅度上升；随着它们加入量的增加，AAP的浊点进一步提高。添加醇类溶剂后，AAP的浊点随醇的结构和性质的不同而升高或降低。

THE CLOUD POINT OF ALLYL ALCOHOL POLYETHER AND ITS INFLUENCING FACTORS

Allyl alcohol polyether(AAP) is a kind of nonionic surfactants. The cloud point (CP) of AAP was experimentally determined. The effects of nonionic surfactant of polyethelene glycol (PEG)，ionic surfactant of sodium dodecylbenzene sulfonate (LAS), polar solvent of alcohol and LAS-alcohol mixture on the cloud point of AAP were investigated. It was found that the CP of AAP did not be changed by addition of PEG, but changed by addition of LAS or LAS-ethanol mixture, which made the CP of AAP greatly increased. The CP of AAP was going up as LAS or LAS-ethanol mixture added, and further going up as their added amounts increased. When alcohol added, the CP of AAP was increased or decreased, which was determined by the structure and properties of the added alcohol, such as their carbon chain and concentration.
