【摘要】 浊点是非离子表面活性剂的一个特性参数,它是非离子表面活性剂溶液由透明变浑浊,和由浑浊变透明的平均温度。聚乙二醇辛基苯基醚是一种非离子表面活性剂,通过实验测定了有机酸、醇、无机盐、聚合物等添加剂对聚乙二醇辛基苯基醚浊点的影响。结果表明,不加任何添加剂时,聚乙二醇辛基苯基醚的浊点为89℃;添加有机酸时,浊点随浓度升高先下降后上升;添加醇时,碳链短的随浓度升高浊点升高,碳链长的随浓度升高而下降;添加无机钠盐时,浊点随浓度升高而下降;添加聚合物时,浊点超过100℃。更多还原

【Abstract】 Cloud point is a characteristic parameter of nonionic surfactant. It is the average temperature of the two temperature points which the nonionic surfactant solution begins changing from transparent to muddy and from muddy to transparent when the temperature decreases. Polyoxyethylene octyphenyl ether is a kind of nonionic surfactant polyoxyethylene octyphenyl ether were studied in this article. It was found that the CP of polyoxyethylene octyphenyl ether was 89℃ when no additives; when organic acids added, the CP decreased first and increased later with the concentration of acids increasing; when alcohols added, the CP increased with the concentration increasing when the carbon chain of alcohols were short, decreased with the concentation increasing when the carbon chain of alcohols were long; when inorganic sodium salts added, the CP decreased with the concentration increasing; when polymer adde, the CP was higher than 100℃.更多还原
