Abstract: Provided is a method of preparing mesopore Y zeolite catalysts with larger mesopore sizes. The method employs swelling agents, and optionally cosolvents. The larger mesopores improve accessibility for mass transport of bulky reactants. In the preparation a swelling agent is used in combination with cetyltrimethylammonium bromide (CTAB). Cosolvents can also be used to affect a strong swelling effect.

Abstract: In one example, a method for converting a first compound into a second compound is provided. The method includes providing the first compound in an entrance of a flow through reactor, wherein the entrance comprises a first catalyst and an oxidant, converting the first compound and the oxidant into the second compound as the first compound and the oxidant contact the first catalyst in the entrance of the flow through reactor while moving towards a tail end of the flow through reactor, and converting the first compound and the oxidant into the second compound via a solid catalyst comprising a white crystalline solid with a titanium content of about 0.5 to about 1.5 weight percent (wt %) in the tail end of the flow through reactor.

Abstract: The present invention is a composition comprising an aqueous dispersion of metal oxide pigment particles coated with an organosilane polymer comprising structural units of an alkyltrihydroxysilane or a salt thereof, a dialkyldihydroxysilane or a salt thereof, and an ancillary alkylsilane triol. The composition of the present invention provides hydrophobicity to pigment particles, thereby imparting water resistance, and allows for high loadings of pigment in water without increased viscosity. The dispersion is further useful for providing stain and corrosion resistance in coatings arising from paints.

Abstract: The present invention relates to a composition comprising a) a stable aqueous dispersion of inorganic pigment particles hydrophobically modified with covalently bonded polysiloxane or silyl groups; and b) a polymeric anionic dispersant; wherein the hydrophobically modified inorganic pigment particles have an average particle size in the range of from 200 nm to 10 μm, and the solids content of the hydrophobically modified inorganic pigment particles is from 10 to 80 weight percent, based on the weight of inorganic pigment particles and water. The composition of the present invention provides a way to improve water resistance in coatings formulations.
