Abstract:
An aromatic hydrocarbon is contacted under hydroalkylation conditions and in the presence of hydrogen with a catalyst comprising at least one ruthenium compound and at least one nickel compound supported on a calcined, acidic, rare earth-treated crystalline zeolite.
Abstract:
A process for the conversion of olefinic hydrocarbons according to the olefin reaction (e.g., the olefin disproportionation reaction) by contacting the olefinic hydrocarbon with a catalyst comprising a coordination compound of molybdenum or tungsten complexed with NO, together with an organoaluminum adjuvant.
Abstract:
Olefins are converted into other olefins having different numbers of carbon atoms by contact with a homogenous catalyst active for disproportionating an olefin into other olefins of both higher and lower carbon atoms comprising a coordination complex of zirconium, titanium or hafnium together with an aluminum-containing catalytic adjuvant.
Abstract:
Internal olefins such as those obtained from a disproportionation of 1-olefins like 1-decene are dimerized over a promoted boron trifluoride catalyst to yield oils useful as lubricant basestock.
Abstract:
A low viscosity slurry is prepared by first making a powder such that the shape of the particles of the powder is granular and then mixing the powder and a suitable dispersant.
Abstract:
Hydroalkylation of aromatic hydrocarbons using an acidic crystalline zeolite type support having ruthenium and nickel thereon, the nickel having been placed thereon responsive to correlation of hydroalkylation selectivity and the amount of alkali metal or alkaline earth metal ion removed from the support during cation exchange when preparing a catalyst. In one embodiment benzene is converted to cyclohexylbenzene.
Abstract:
Dihydropyrans, such as 3,4-dihydro-4-methyl-2[H]-pyran, are prepared from unsaturated alcohols, such as 3-methyl-3-buten-1-ol, by reaction with carbon monoxide and hydrogen employing a Group VIII or VIB catalyst.
Abstract:
An aromatic hydrocarbon is contacted under hydroalkylation conditions and in the presence of hydrogen with a composition comprising at least one platinum compound supported on a calcined, acidic, nickel and rare earth-treated crystalline zeolite which additionally has a halide content sufficient to promote the selectivity of the composition to produce a desired cycloalkyl aromatic hydrocarbon.
Abstract:
An aromatic hydrocarbon is contacted under hydroalkylation conditions and in the presence of hydrogen with a composition comprising at least one rhodium or palladium compound or mixture thereof supported on a calcined, acidic, nickel and rare earth-treated crystalline zeolite.
Abstract:
Acid catalyzed cleavage products of hydrocarbyl aromatic hydroperoxides are subjected to extractive distillation employing a hydrocarbon solvent. In a specific embodiment a mixture containing cyclohexylbenzene, phenol and cyclohexanone obtained from the acid catalyzed cleavage of cyclohexylbenzene hydroperoxide is subjected to extractive distillation employing hexadecane.
