  • Patent number: 6743749
    Abstract: A Ti—O—N film is formed on an SiO2 substrate by sputtering. For example, TiO2 is used as a target and nitrogen gas is introduced into the atmosphere. Crystallization is carried out by a post-sputtering heat treatment. Then a charge separation material such as Pt is supported on the Ti—O—N film. With the fabricated TiO2 crystals, the Ti—O—N film containing nitrogen exhibits a good catalytic reaction by using visible light as acting light. Since the charge separation material captures electrons or positive holes, recombination of electrons and positive holes is effectively prevented, and consequently more efficient photocatalytic reaction is performed. It is preferable to form a photocatalyst material film (Ti—Cr—O—N film) by sputtering the SiO2 substrate by use of TiO2 and Cr as the target in a nitrogen atmosphere. Crystallization is performed by a post-sputtering heat treatment.

  • Patent number: 6723823
    Abstract: Mixed alkali metal salts of phosphoric acid in combination with a co-catalyst such as tetramethylammonium hydroxide (TMAH) are excellent transesterification catalysts for use in the preparation of polycarbonate from bisphenol A and diphenyl carbonate. The mixed alkali metal phosphate salts were shown by kinetic measurements made on a model system composed of p-tert-octylphenol and bis(p-cumylphenyl) carbonate to be inherently more potent catalysts than salts of phosphoric acid comprising a single alkali metal ion. In addition to providing higher rates of polymerization, the new catalysts were shown to provide polycarbonates containing reduced levels of Fries rearrangement product relative to polymerization reactions catalyzed by conventional catalyst systems such as sodium hydroxide together with TMAH co-catalyst.

  • Patent number: 6602817
    Abstract: Functionalized amine derivatives are prepared by reacting an amine, a carbonyl derivative, and an organoboron compound under mild conditions. Organoboronic acids react with amines and alpha-hydroxy aldehydes to give anti-alpha-amino alcohols with very high diastereoselectivities (>99% de). When optically pure alpha-hydroxy aldehydes are used in this process, no racemization occurs and the products are obtained with very high enantioselectivities (>99% ee). The reaction also works with unprotected glyceraldehyde to give the corresponding amino diol derivatives, while unprotected carbohydrates give the corresponding amino polyols. The chiral amino alcohol products of this process or their derivatives, react further with metals or non-metals to give adducts that are effective catalysts for a variety of asymmetric reactions. Overall, the present invention relies on the facile synthesis of the chiral amino alcohol ligands for the rapid construction of combinatorial libraries of chiral catalysts.

  • Publication number: 20030130448
    Abstract: A process for making an ultra-high-molecular-weight polyethylene (UHMWPE) is disclosed. The process is performed with a supported quinolinoxy-containing single-site catalyst in the presence of a non-alumoxane activator, but in the absence of an &agr;-olefin, an aromatic solvent, and hydrogen. The process significantly increases the catalyst activity and the UHMWPE produced has improved tensile and impact properties.
