摘要
以壬基酚聚氧乙烯醚(TX-10)为原料,以P2O5为磷化剂,合成壬基酚聚氧乙烯醚磷酸酯。考察了P2O5的投料方式,原料配比,酯化时间,酯化温度对酯化率的影响,确定了最佳酯化条件:在40℃强烈搅拌下分批加入P2O5,配比为3.2/1(mol/mol),酯化温度75℃,酯化时间4.5h,在该条件下合成的产品酯化率为78.9%。同时研究了壬基酚聚氧乙烯醚磷酸酯的性能。
Phosphate polyoxyethylene nonyl phenol(PPNP) was Synthesized with polyoxyethylene nonyl phenol(TX-10) and phosphorus pentoxide . The effects of the feeding way of phosphorus pentoxide, the ratio of TX-10 to P2O5, the temperature and reaction time on the yield were investigated. The proper feeding way was : feeding at batches and stirring strongly at 40℃.The optimum reaction conditions include TX-10/P2O5, the ratio of 3.2/1(mol/mol), the temperature of 75℃ the reaction time of 4.5h .Under these conditions ,the rate of esterifying yield reached 78.9%. The surfactant property of the product was also studied.
