Abstract: A heterogeneous catalyst that is a combination of rhodium, zinc, iron, a fourth metal and at least one metal selected from alkali metals and alkaline earth metals on a catalyst support (e.g. at least one of silica, alumina, titania, magnesia, zinc aluminate (ZnAl2O4), magnesium aluminate (MgAl2O4), magnesia-modified alumina, zinc oxide-modified alumina, zirconium oxide-modified alumina, and zinc oxide) and use of the catalyst in converting an alkylene to an oxygenate that has one more carbon atom than the alkylene.

Abstract: Oxidatively halogenate methane by placing a feedstream that comprises methane, a source of halogen, a source of oxygen and, optionally, a source of diluent gas in contact with a first catalyst (e.g. a solid super acid or a solid super base) that has greater selectivity to methyl halide and carbon monoxide than to methylene halide, trihalomethane or carbon tetrahalide. Improve overall selectivity to methyl halide by using a second catalyst that converts at least part of the feedstream to a mixture of methyl halide, methylene halide, trihalomethane, carbon tetrahalide and unreacted oxygen, and placing that mixture in contact with the first catalyst which converts at least a portion of the methylene halide, trihalomethane and carbon tetrahalide to carbon monoxide, hydrogen halide and water.

Abstract: Convert an alkylene to a product stream that comprises an alkanol by subjecting a gaseous combination of a) an alkylene selected from ethylene, propylene or a combination thereof, b) carbon monoxide, c) hydrogen and, optionally, d) at least one hydrocarbon or gas diluent other than ethylene or propylene to reductive hydroformylation conditions in combination with a solid phase, sulfided, heterogeneous catalyst.

Abstract: The present invention provides a method for simplifying manufacture of a mixed alcohol or mixed oxygenate product from synthesis gas. The mixed alcohol or mixed oxygenate product contains ethanol and other oxygenates with two or more carbon atoms per molecule. The method includes stripping a portion of carbon dioxide and inert gases contained in a mixed alcohol synthesis reaction product using a methanol-containing stream, such as one produced as part of the method, as a medium to absorb said carbon dioxide and inert gases and recycling light products and heavy products to one or more of synthesis gas generation, mixed alcohol synthesis and separation of desired mixed alcohol or mixed oxygenate products from other components of a mixed alcohol synthesis stream.

Abstract: Metal cyanide catalysts are complexed with complexing agents that are miscible in poly(propylene oxide) at higher temperatures and immiscible at lower temperatures.

Abstract: A polyether composition comprised of a polyether, a functionalizing catalyst and a metal cyanide catalyst is formed by forming a functionalized initiator compound by reacting a precursor initiator compound with a functionalizing compound and a functionalizing catalyst to form the functionalized initiator compound, forming a mixture of the functionalized initiator compound containing at least a portion of the functionalizing catalyst, an alkylene oxide and a metal cyanide catalyst complex, and subjecting the mixture to conditions sufficient to activate the catalyst complex and to alkoxylate the functionalized initiator compound to form the polyether. The functionalized initiator compound may be of a vegetable oil, animal fat or modified vegetable oil or modified animal fat. The functionalizing catalyst may be a tin, titanium, iodine, rhodium, nickel, acid or enzyme catalyst.

Abstract: Complexes of a metal cyanide polymerization catalyst and certain monomer complexing agents provide a method whereby heterogeneous, active metal cyanide catalysts can be prepared. The catalysts are useful alkylene oxide polymerization catalysts that are easily separated from the polymerization product and recycled.

Abstract: Double metal cyanide catalysts (DMC) are complexed with complexing agents that are miscible in poly(propylene oxide) at higher temperatures and immiscible at lower temperatures. The complexing agent is a poly(ethylene oxide) polymer or a copolymer having a poly(ethylene oxide) block. The catalyst is easily removed from a polyether polyol.

Abstract: Metal cyanide catalyst dispersions in initiator compounds and/or polyethers are prepared by reacting an acidic metal cyanide compound with an insoluble metal salt in a medium that is a solvent for the acidic metal cyanide compound but not the metal salt. The resulting catalyst slurry may be combined with an initiator and stripping to form a catalyst/initiator or catalyst/polyether slurry. Using this method, an active alkylene oxide polymerization catalyst is prepared, and the preparation method is greatly simplified. Further, it is not necessary to use a separate organic complexing agent in the preparation.

Abstract: Certain alcohol initiators containing halogen, aldehyde, ketone or nitro substitution can be alkoxylated with excellent efficiency and low production of by-products using an metal cyanide catalyst. The products contain halogen, aldehyde, ketone or nitro groups that can undergo subsequent reactions to form amino groups.
