Abstract: Tetraphosphorous ligands are combined with transition metal salts to form catalysts for use in hydroformylation, isomerization-hydroformylation, hydrocarboxylation, hydrocyan-ation, isomerization-formylation, hydroaminomethylation and similar related reactions.

Abstract: A method and catalyst system for economically producing aromatic carbonates from aromatic hydroxy compounds. In one embodiment, the present invention provides a method of carbonylating aromatic hydroxy compounds by contacting at least one aromatic hydroxy compound with oxygen and carbon monoxide in the presence of a carbonylation catalyst system that includes a catalytic amount of an inorganic co-catalyst containing titanium. In various alternative embodiments, the carbonylation catalyst system can include an effective amount of a palladium source and an effective amount of a halide composition. Further alternative embodiments can include catalytic amounts of various inorganic co-catalyst combinations.

Abstract: A stable substantially cubic perovskite crystalline structure of at least one strontium-doped lanthanum cobalt oxide (LSC) having a stabilizing amount of at least one cerium gadolinium oxide (CGO) therein.

Abstract: A process for producing an exhaust-gases-purifying catalyst includes the steps of loading an NO.sub.x adsorbent on a porous support, carbonating the porous support with the NO.sub.x adsorbent loaded, thereby converting the NO.sub.x adsorbent into carbonate, and loading a noble metal catalyst ingredient on the porous support with the carbonate loaded. The process can produce an exhaust-gases-purifying catalyst on which the NO.sub.x adsorbent and the noble metal catalyst ingredient are loaded in large amounts and which can stably and efficiently purify NO.sub.x during the fuel-lean side (i.e., in the oxygen-rich atmospheres) driving.

Abstract: There is provided a three-step method for removing the residue of an organic directing agent from as-synthesized zeolites. The first step involves contacting the as-synthesized zeolite with an aqueous solution of a fluorosilicate salt such as ammonium fluorosilicate. The second step involves ion-exchanging the zeolite with an alkali metal or alkaline earth metal salt such as KCl. The third step involves calcining the ion-exchanged zeolite. This method is particularly useful for removing the residue of an organic directing agent from ZSM-18.
