    Abstract: A pyrochlore-type oxide represented by a general formula A2B2O7-Z is prepared by precipitate formation, where A and B each represent a metal element, where Z represents a number of at least 0 and at most 1, where A contains at least one element selected from a group consisting of Pb, Sn, and Zn, and where B contains at least one element selected from a group consisting of Ru, W, Mo, Ir, Rh, Mn, Cr, and Re. Impurities are then sufficiently removed through washing and drying processes, and the pyrochlore-type oxide is calcined under controlled conditions. This allows the crystallinity of the pyrochlore-type oxide, which contained amorphous parts immediately after the production of the precipitate, to be increased so that the resistance to acid can be improved while preventing particle aggregation.

  • Patent number: 8105971
    Abstract: A process for forming a catalyst useful for the production of an olefin from a hydrocarbon is disclosed. The process may include: admixing at least one of elemental metals and compounds to form a multi-metal composition comprising Mo, V, Nb, Te and at least one of Ni and Sb; adjusting the pH of the multi-metal composition by adding nitric acid; drying the acidified multi-metal composition; calcining the dried multi-metal composition; and grinding the calcined multi-metal composition. The ground multi-metal composition may then be sized or shaped to form a mixed metal oxide catalyst. Alternatively, the ground multi-metal composition may be treated with an acid, optionally annealed, and sized or shaped to form a mixed metal oxide catalyst.

  • Patent number: 7977446
    Abstract: This invention relates to an organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has low activity in the absence of oxygen. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.
