  • Water-wettable silylated metal oxides
    Patent number: 8333946
    Abstract: Partly hydrophobic metal oxides are prepared by silylating a metal oxide with I) an organosilane of the formula R1nSiX4-n where n is 1, 2 or 3 or mixtures of these organosilanes, R1 each being an identical or different monovalent, optionally halogenated hydrocarbon radical having 1 to 24 carbon atoms, and being saturated, aromatic, monounsaturated, or polyunsaturation, X being halogen, a nitrogen-containing radical, OR2, OCOR2, O(CH2)xOR2, R2 being hydrogen or a monovalent hydrocarbon radical having 1 to 12 carbon atoms, x being 1, 2 or 3; or II) an organosiloxane composed of units of the formula (R13SiO1/2), and/or (R12SiO2/2), and/or (R1SiO3/2), the number of R1 units in one organosiloxane being at least 2; I and II used individually or in any desired mixture in a total amount of from 0.015 mmol/g to 0.15 mmol/g per 100 m2/g of metal oxide BET surface area.
