单油酸聚乙二醇400磷酸酯(盐)的合成与性能

Preparation and performance of mono-oleic polyethylene glycol(400)phosphate

报道了单油酸聚乙二醇(400)磷酸酯的合成、分析和应用;测试了其表面活性,如表面张力、润湿性、泡沫性和乳化性能等。研究发现,通过酯交换法,合成的这种产品同其他阴离子及非离子表面活性剂比较,有更好的乳化性能。乳化效力是吐温80的1 5倍多(以油水分离时间计算),也是同类其他磷酸酯产品的1倍～2倍多。同时具有低的泡沫,对人体皮肤无刺激性,适合使用于各种领域。

The preparation,analysis and application of mono-oleic polyethylene glycol(400)phosphate were presented.Properties of the product,such as surface tension,wetting,foaming,emulsifying and skin irritation were investigated.The product obtained by transesterification displays better emulsifying and lower foaming property then that of other anionic and non-ionic surfactants.Emulsifying power achieves 1.5 times as large as that of Tween 80(indicated by oil-water separating time)and 1～2 times of other phosphate products.The product can be used in various industrial fields.
