  • Patent number: 10414661
    Abstract: A method of producing a silicon hydride oxide-containing organic solvent (coating solution) is provided with which a silicon hydride oxide coating film can be formed on a substrate. Using the silicon hydride oxide-containing organic solvent makes it unnecessary to place a coating solution in non-oxidizing atmosphere at the time of coating or to heat the substrate after coating because the silicon hydride oxide is formed in the coating solution before it is coated. The method includes blowing an oxygen-containing gas through an organic solvent containing a silicon hydride or a polymer thereof. The silicon hydride oxide may contain a proportion of (residual Si-H groups)/(Si-H groups before oxidation) of 1 to 40 mol %. The silicon hydride can be obtained by reacting a cyclic silane with a hydrogen halide in the presence of an aluminum halide, and reducing the obtained cyclic halosilane.

  • Patent number: 10399034
    Abstract: The high temperature titanium-catalyst comprises a body, the body having a hot gas inlet and a hot gas outlet. The body comprises an array of titanium containing catalytic elements, wherein the array of titanium containing catalytic elements is arranged such that hot gas containing an amount of hexavalent chromium Cr(VI) may enter the body at the hot gas inlet, may pass through the array of titanium containing catalytic elements and may leave the body at the hot gas outlet. When the titanium-catalyst is in use, Cr(VI) in the hot gas containing an amount of Cr(VI) reacts with titanium oxide in a surface layer of the titanium containing catalytic elements, whereby the Cr(VI) is reduced to trivalent chromium Cr(III) thus reducing the amount of Cr(VI) in the hot gas containing an amount of Cr(VI).
