多芳基酚聚氧乙烯醚磷酸酯盐的合成

Synthesis of Polyarylphenol-Polyoxyethylene Ether Phosphate

以多芳基酚聚氧乙烯醚(PPE)和五氧化二磷为原料,合成了一种阴离子表面活性剂--多芳基酚聚氧乙烯醚磷酸酯三乙醇胺盐(TPEP),较佳的工艺条件为:n(PPE):n(P2O5 )为1.9:1, 添加剂0.5 g,四氯化碳15 mL, 酯化反应温度为65～70 ℃,反应时间5 h,单酯质量分数为61.3%,性能测试结果表明,这是一种良好的表面活性剂.

A type of anionic surfactant polyarylphenol - polyoxyethylene ether phosphate （TPEP） was synthesized with PPE and P2O5 as raw materials. The best process parameters were obtained as：n （PPE） / n（P2Os） 1.9 ： 1; additive 0.5 g; tetrachloride 15 mL; reaction temperature 65 ～ 70℃; reaction time 5 h. The content of monophosphate is 61.3%. The result of the properties determined showed that it is a good surfactant.
