  • Patent number: 6355490
    Abstract: The present invention relates to a process of coding and identifying individual members of a chemical combinatorial library synthesized on a plurality of solid supports which undergo mix and split synthesis. The process provides for tagging the solid supports with a coding identifier that is attached to the solid support and which can be decoded by infrared or raman spectroscopy when directly attached to the support.

  • Patent number: 6344568
    Abstract: This invention relates to a method for producing a partially oxidized organic compound, e.g., an unsaturated aldehyde/carboxylic acid having three or more carbon atoms, or an organic acid anhydride/nitrile compound having four or more carbon atoms. This method requires a catalyst prepared by treating a carrier in such a manner that water used in the treatment achieves specific resistance.

  • Patent number: 6329549
    Abstract: A process for methylating an alpha carbon adjacent to an electron withdrawing group includes reacting dimethyl ether with a molecule containing the alpha carbon and the electron withdrawing group to substitute a methyl group on the alpha carbon. The process can be conducted in a vapor phase and can be represented by Equation I: R(CH2)nCH2-EWG+CH3OCH3→R(CH2)nCH(CH3)-EWG+CH3OH  (I) where EWG is the electron withdrawing group, and R is H when n is 0, 1 or 2, and R is alkyl, EWG or aryl when n>2. For example, the molecule reacted with dimethyl ether can be acetic acid, propionic acid, methyl acetate, methyl propionate, acetonitrile, propionitrile and acetone. The process is catalyzed by an acid catalyst containing a Lewis acid functionality. When the electron withdrawing group is an acid, a methyl ester can be formed by esterifying the electron withdrawing group with methanol liberated from dimethyl ether.

  • Patent number: 6281378
    Abstract: Vanadium-containing catalysts are obtained by using polyvanadic acid as a source of vanadium. Vanadium-containing catalysts are obtained by mixing catalyst components other than vanadium, or their precursors, with a polyvanadic acid sol which is formed by ion-exchanging a metavanadic acid aqueous solution with a proton-type cation-exchange resin and performing polycondensation, and by drying and/or calcining the mixture.

  • Patent number: 6255428
    Abstract: An epoxy group-bearing organopolysiloxane or organosilane is prepared by effecting addition reaction between an organohydropolysiloxane or organohydrosilane and an alkenyl group-bearing epoxy compound in the presence of an addition reaction catalyst. A cyano group-bearing compound is co-present in the reaction system. The end organopolysiloxane or organosilane having a stabilized viscosity is obtained while avoiding gelation or thickening during reaction.
