  • CATALYST FOR SYNTHESIZING METHANOL OR ITS PRECURSOR, METHOD FOR PREPARING THE CATALYST AND METHOD FOR PRODUCING METHANOL OR ITS PRECURSOR USING THE CATALYST
    Publication number: 20180118772
    Abstract: Disclosed is a novel catalyst having amine ligands for synthesizing methanol or its precursor. When the catalyst is allowed to react with an alkane in the presence of an acid, at least one C—H bond of the alkane is catalytically oxidized. Therefore, the catalyst is suitable for use in forming an alkyl ester from an alkane.

  • Process of forming an amide
    Patent number: 9334230
    Abstract: A process is provided for the synthesis of an amide. A primary or secondary amine and a primary alcohol, with the amine and the alcohol being either moieties of different reactants or moieties of the same molecule, are contacted in the presence of a Ruthenium (II) catalyst. The Ruthenium (II) catalyst is free of a phosphine ligand. The process is also carried out in the absence of a phosphine. Providing the Ruthenium (II) catalyst includes providing an N-heterocyclic carbene.
