摘要/Abstract

摘要： 研究五氧化磷的投料方式、反应物的用量比、反应温度和反应时间等因素对合成的异辛醇聚氧乙烯醚(C8H17 (EO) 4OH) 磷酸酯性能的影响,得到优化的异辛醇聚氧乙烯醚磷酸酯的合成工艺条件:在强烈搅拌下,分批投入P2O5 ,加料时的温度不超过45 ℃, n (C8H17 (EO) 4OH) ∶n (P2O5 ) = 2∶1 ,酯化温度为70 ℃,酯化时间为4 h ,在温度70 ℃时加入定量的水再水解2 h。实验结果表明按优化工艺条件合成的异辛醇聚氧乙烯醚磷酸酯在质量浓度为200 gPL的强烧碱溶液中的渗透时间为4 s ,具有良好的耐强碱渗透能力。

Abstract: The effects of feeding way of phosphorus pentoxide , ratio of C8H17 ( EO) 4OH to P2O5 , reaction
temperature and time on the synthesized isooctanol polyethenoxy ether phosphate were investigated. Its optimum
synthesis technology conditions were as follows : feeding at batches while stirring tempestuously at 45 ℃, the
ratio of n (C8 H17 (EO) 4OH) ∶n (P2O5 ) = 2∶1 ,esterifying at 70 ℃for 4 h , and add given volume of water at
70 ℃for hydrolysing 2 h. The experimental results indicated that the isooctanol polyethenoxy ether phosphate
synthesized under the optimum process conditions has good resistance to strong alkali penetration , whose
penetration time is 4 s when its mass concentration is 200 gPL in sodium hydroxide solution
