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 (ZnAlO), magnesium aluminate (MgAlO), 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.

Heterogeneous catalyst and its use

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.

Oxidative mono-halogenation of methane

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.

Reductive hydroformylation of an alkylene to an alkanol

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. The present invention also provides downstream processing of the mixed alcohol or mixed oxygenate product by subjecting the product to a dehydration step in order to convert at least ethanol, preferably at least ethanol and propanol, to their corresponding olefins (e.g. ethylene and propylene).

Mixed alcohol synthesis with enhanced carbon value use

The present invention relates to new (meth)acrylate compositions, their preparation and their use in ultraviolet light curable applications such as coatings, inks and adhesives.

Reactive (meth)acrylate monomer compositions and preparation and use thereof

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

Method for preparing metal cyanide catalyst complexes using partially miscible complexing agents

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.

Method for preparing metal cyanide catalysts using polymerizable complexing agents

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.

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.

Method for preparing metal cyanide catalysts using insoluble metal salts

There are disclosed silicone polyether compositions, methods for making them and their uses. The compositions are based on polyethers initiated by non-isomerizing alkenyl or alkynyl alcohols.

Certain silicone polyethers, methods for making them and uses

Metal cyanide catalyst dispersions in initiator compounds and/or polyether are prepared by reacting an acidic metal cyanide compound a zero valent metal in a medium that is a solvent for the acidic metal cyanide compound. The resulting catalyst slurry may be combined with an initiator and/or polyether and stripped 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 necessary to use a separate organic complexing agent in the preparation.

Method for preparing metal cyanide catalysts using zero valent metals

Ethoxylations of various initiator compounds are performed in the presence of metal cyanide catalysts. The catalysts surprisingly form a wide variety of polyether products that in most cases contain only small amounts of high molecular weight poly(ethylene oxide).

Polymerization of ethylene oxide using metal cyanide catalysts

Crosslinked organic polymers such as styrene-divinylbenzene copolymers contain pendant phosphazene or phosphazenium groups. These polymers are excellent alkylene oxide polymerization catalysts.

Polymerizing alkylene oxide with phospazen (IUM) crosslinked polymer

Metal cyanide catalyst dispersions in initiator compounds are prepared by precipitating the catalyst in an inert organic compound, mixing the resulting slurry with the initiator and stripping off the inert organic compound. Using this method, an active alkylene oxide polymerization catalyst is prepared. It is not necessary to use a separate organic complexing agent in the preparation.
