阅读说明：本技术 用酸官能化二氧化硅和金属硅酸盐提纯粗聚环氧烷聚合物 (Purification of crude polyalkylene oxide polymers with acid-functionalized silica and metal silicates ) 是由 A.巴格里夫 G.E.希克斯 于 2018-03-13 设计创作，主要内容包括：一种提纯含有催化剂,如氢氧化钾的粗聚环氧烷聚合物的方法。该方法包含使粗聚环氧烷聚合物与从聚环氧烷聚合物中有效除去催化剂的量的包含酸官能化硅酸盐,如含有至少一种酸的酸官能化硅酸镁吸附剂的组合物接触。这种方法实现改进的聚环氧烷聚合物中除去催化剂。(A process for purifying a crude polyalkylene oxide polymer containing a catalyst, such as potassium hydroxide. The process comprises contacting a crude polyalkylene oxide polymer with an amount of a composition comprising an acid-functionalized silicate, such as an acid-functionalized magnesium silicate adsorbent comprising at least one acid, effective to remove catalyst from the polyalkylene oxide polymer. This process achieves improved catalyst removal from the polyalkylene oxide polymer.)
