Poly(oxy-1,2-ethanediyl), .alpha.,.alpha.,.alpha.-1,2,3-propanetriyltris.omega.-hydroxy-, phosphate性质、用途与生产工艺

生产方法 

一般先将丙三醇氧乙基化,然后再磷酸酯化。丙三醇的氧乙基化系将丙三醇与作为催化剂的粉状苛性碱混合物在惰性气体的保护下加热到150℃,然后按环氧乙烷∶丙三醇等于2∶1的摩尔比缓慢加入环氧乙烷,此期间保持温度为150-160℃。环氧乙烷加完后,再保温一段时间(例如1.2h),丙三醇的氧乙基化即可视为完成。此过程中所加的苛性碱量,约占丙三醇和环氧乙烷总量的0.1%。所得聚氧乙烯醚丙三醇的磷酸酯化过程,系将它与黏度控制剂正丙醇按4.5∶1的质量比加入反应釜中,预热至50℃,然后按五氧化二磷∶聚氧乙烯醚丙三醇=1∶(1.1~1.2)的质量比逐渐将五氧化二磷加到反应釜中,控制温度,使之不超过125~135℃。五氧化二磷加完后,保温一段时间,釜中物质变为透明时,酯化过程即可视为完成。加水使磷酸酯冷却并达到预期含量备用。
