Patent number: 5233095Abstract: A process for the manufacture of resorcinol is described which relies upon the intermediacy of a .alpha.,.beta.-unsaturated ketone which can be reacted with a hydroxy moiety-containing compound to obtain a resorcinol precursor which is subsequently converted to resorcinol. In a specific embodiment, 2-cyclohexenone is reacted with water to obtain 3-hydroxycyclohexanone which is dehydrogenated to resorcinol. In another embodiment, 2-cyclohexenone is oxidized to cyclohexane-1,3-dione which is dehydragenated obtain resorcinol.Type: GrantFiled: July 16, 1991Date of Patent: August 3, 1993Assignee: Catalytica, Inc.Inventors: Jere D.

Patent number: 5026942Abstract: The selective isopropylation of a naphthyl compound to diisopropylnaphthalene enhanced in the 2,6-diisopropylnaphthalene isomer is obtained in the presence of an acidic crystalline molecular sieve catalyst having twelve membered oxygen rings. The catalyst pore aperture dimension range from 5.5 .ANG. to 7.0 .ANG.. The user of these shape selective catalysts results in a diisopropylnephthalene stream which is enhanced in .beta. isomers and enhanced in the desired 2,6-diisopropylnaphthalene isomer. A particularly preferred catalyst is synthetic Mordenite having a specific Si/Al ratio and NMR characteristics. Specific catalyst modifications are also described to improve selectivity to the desired 2,6-diisopropylnaphthalene isomer.Type: GrantFiled: December 12, 1989Date of Patent: June 25, 1991Assignee: Catalytica, Inc.Inventors: Jere D.

Patent number: 5003120Abstract: A process for the selective manufacture of 2,6-diisopropylnaphthalene from naphthalene advantageously combines an equilibration reactor to enhance the amount of monoisopropylnaphthalene fed to the alkylation reactor, and the use of a shape selective catalyst in the alkylation reactor, to obtain an alkylation reaction product in which the 2,6-diisopropylnaphthalene isomer comprises greater than 39 mole percent of the total diisopropylnaphthalene obtained. Further, this combination of reaction steps and conditions produces a reaction product in which the ratio of 2,6-diisopropylnaphthalene to 2,7-diisopropylnaphthalene is greater than 1.0, preferably greater than 1.2. Recycled process components are fed to the equilibration reactor where they are combined with fresh naphthalene feed to provide a monoisopropylnaphthalene enriched feed to the alkylation reactor.Type: GrantFiled: January 27, 1989Date of Patent: March 26, 1991Assignee: Catalytica, Inc.Inventors: Stanley F.

Patent number: 4853357Abstract: The additional of redox-active metal components and ligands, alternatively or simultaneously, results in increased conversion and selectivity in the palladium-catalyzed oxidation of olefins to carbonyl products in the presence of polyoxoanions. In preferred modes, heteropolyoxoanions and Isopolyoxoanions containing tungsten, molybdenum and vanadium, individually or in combination, are described. The use of copper as the redox-active metal component shows reduced allylic reactivity. The elimination of chloride from the catalyst system provides substantial engineering advantages over the prior art, particularly, the reduction of corrosion and chloro-organic by-product formation. The use of redox-active metal components and/or ligands makes the palladium-polyoxoanion catalyst system industrially practicable.Type: GrantFiled: September 30, 1987Date of Patent: August 1, 1989Assignee: Catalytica AssociatesInventors: Janis Vasilevskis, Jacques C.
