【摘要】 以五氧化二磷、正辛醇为原料合成磷酸酯表面活性剂。通过正交试验考察反应时间、反应温度和原料摩尔比对合成磷酸酯表面活性剂的影响,结果表明,3因素中反应时间对磷酸酯表面活性剂的影响最大。最佳反应条件为:反应时间5 h,反应温度53℃,原料摩尔比(正辛醇∶五氧化二磷)2.73。在该条件下,磷酸酯表面活性剂的产率可达85%。更多还原

【Abstract】 Phosphate surfactant was synthesized via the reaction of octanol with P2O5.Best reaction conditions were found by orthogonal test.Result showed that reaction time was the main affecting factor.The optimal reaction conditions were as follows,reaction time 5 h,temperature 53 ℃,n(octanol)∶ n(P2O5)=2.73∶1.In the optimal reaction conditions,the yield of phosphate surfactant could reach to 85%.更多还原
