摘要： The present invention provides a continuous process for the conversion of sodium silicate to silicic acid, wherein a moving bed of a protonated ion exchange resin is contacted with an inlet stream of sodium silicate to provide an outlet stream of silicic acid. The outlet stream of silicic acid produced thereby can be processed into a variety of silica products. The outlet moving bed of spent sodium-enriched ion-exchange resin is continuously regenerated into protonated ion-exchange resin by contacting the spent resin with an inlet stream of acid of sufficient strength to exchange the sodium ions in the spent resin with a proton. The regenerated protonated ion-exchange resin is continuously recycled back into the sodium silicate stream for further production of silicic acid.

摘要： 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.

摘要： A method of preparing treated silica is described. The method comprises mixing a hydrolyzable silica precursor such as methyltrichlorosilane with water, an acid (e.g., hydrochloric acid) and a hydrophobing agent capable of rendering polar silanol groups hydrophobic, such as trimethylchlorosilane. The treated silica is then recovered from the mixture. The inventive method provides a number of mechanisms for controlling the physical properties (e.g., particle size, surface area, etc.) of the treated silica. For example, the rate of hydrolysis of the silica precursor, which impacts these physical properties, can be regulated by the nature and concentration of the acid used in the reaction.

摘要： The present invention provides a method of treating silica, wherein dry silica is contacted with a reaction medium consisting essentially of concentrated aqueous acid and a hydrophobing agent selected from the group consisting of organosiloxanes and organochlorosilanes. The silica is then reacted with the hydrophobing agent in the reaction medium for about 90 minutes or less at a temperature from about 10 °C to about 40 °C to provide a hydrophobic treated silica. The hydrophobic treated silica then is recovered.
