    Abstract: The present invention provides a method of treating silica wherein silica is reacted with a di- or tri-functional organosilane in an aqueous acid medium to provide a crude organosilane-capped silica product containing organosilicon impurities. The organosilicon impurities are extracted from the crude product with an organic liquid to provide a purified product consisting essentially of organosilane-capped silica. The purified product is dried to provide a dry organosilane-capped silica. The aqueous acid medium can include a displacing reagent which displaces at least one reactive functional group of the di- or tri-functional organosilane. The present invention further provides continuous methods of treating silica with di- and tri-functional organosilanes, wherein the organic liquid and/or the organosilicon impurities are recycled and reused.

    Abstract translation: 本发明提供了一种处理二氧化硅的方法，其中二氧化硅与含水酸性介质中的二官能或三官能有机硅烷反应，以提供含有有机硅杂质的粗有机硅烷封端二氧化硅产物。 用有机液体从粗产物中提取有机硅杂质，以提供基本上由有机硅烷封端的二氧化硅组成的纯化产物。 将纯化的产物干燥以提供干燥的有机硅烷封端二氧化硅。 含水酸性介质可以包括置换试剂，其置换二官能或三官能有机硅烷的至少一个反应性官能团。 本发明还提供了用二 - 和三官能有机硅烷处理二氧化硅的连续方法，其中有机液体和/或有机硅杂质被再循环和重复使用。
