    摘要: An improved process is provided for forming ketones from the corresponding olefins in the vapor phase in the presence of water vapor employing a heterogeneous catalyst comprising a molybdenum disulfide catalyst formed by the thermal decomposition of a thiomolybdate compound. It has been surprisingly found that these catalysts effect the formation of ketones in high selectivities with minimal selectivities to the undesirable carbon dioxide and carbon monoxide by-products.

    摘要: Palladium catalysts employed in the hydrogenation of reducible cyclic organic compounds containing deleterious nitrogen impurities are reactivated according to a process comprising separating spent catalyst from the hydrogenation reaction mixture; contacting the separated spent catalyst in a liquid reaction medium with a reactivating agent selected from the group consisting of alkali metal and alkaline earth metal bicarbonates, carbonates, nitrates, chlorides, fluorides, hydroxides and mixtures thereof, to reactivate the catalyst; and recovering the reactivated catalyst for recycle to the hydrogenation reaction mixture.

    摘要: A process for the conversion of heavy bottoms from aromatic alkylation known as "flux oil" and containing heavier polyalkylaromatic compounds, in which the heavier polyalkylates are fed along with aromatic to a reactor containing an acidic zeolite catalyst for conversion to light mono-, and poly alkylaromatic compounds. The light polyalkylates may then be transalkylated with benzene to form additional monoalkylate.

    摘要: An improved process is provided for forming ketones from the corresponding olefins in the vapor phase in the presence of water vapor employing a heterogeneous catalyst comprising rhenium compounds and complexes, optionally containing at least one metal compound or complex selected from the group consisting of Group VIB metals and Group VIII noble metals, and mixtures thereof. It has been surprisingly found that these catalysts effect the formation of ketones in high selectivities with minimal selectivities to the undesirable carbon dioxide and carbon monoxide by-products.
