A lube-oil range hydrocarbon mixture is produced by the oligomerization of a branched olefin mixture which contains olefins of 6 to 16 carbon atoms and has a degree of branching of about 10 to 50 mole percent of branched olefins; the lube-oil range hydrocarbon is obtained by separating and hydrogenating the oligomerized olefins.

Hydrocarbon synthesis

An aromatic hydrocarbon is contacted under suitable hydroalkylation conditions with a composition comprising a calcined, acidic, nickel and rare earth-treated crystalline zeolite.

Hydroalkylation catalyst and methods for producing and employing same

A method for producing terephthalic acid from potassium benzoate in which the potassium benzoate is charged to the reactor in powdered form as a low viscosity slurry of potassium benzoate in terphenyl.

Process of producing terephthalic acid

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.

Olefin dimerization

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.

Low viscosity slurry and method of preparing same

Compositions comprising tin (II) and antimony (III) dihydrocarbylphosphorodithioates are disclosed which are usefully employed to treat metals contaminated catalytic cracking catalysts. A method for the preparation of the tin compound is also disclosed comprising reacting a dihydrocarbyl phosphorodithioic acid with a tin (II) salt of a carboxylic acid to form a reaction product which can be employed in conjunction with the antimony compound without further purification.

Passivating agent composition and method for its preparation

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.

Hydroalkylation using nickel-ruthenium catalyst on zeolite type support

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.

Preparation of dihydropyrans

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.

Hydroalkylation process and a composition and process for producing said

Novel compositions and novel hydroformylation catalysts are prepared by the interaction of an organorhodium halide of the formula (L).sub.n Rh(X).sub.m, wherein X is chlorine, bromine or iodine, L is a cyclic diene or a cyclic triene, n equals 1 or 2, m equals 1 or 2, the sum of n+m equals 2 or 3; hydrazine or a hydride of Group IA, IIA or IIIA metals; and a phosphorus containing adjuvant of the formula L'.sub.3 P, wherein each L' individually represents aryl, aryloxy, alkaryl, aralkyl, alkaryloxy, aralkoxy, alkyl or alkoxy radicals. The hydroformylation catalysts promote the conversion of olefins to linear aldehydes.

Rhodium hydroformylation catalyst

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.

Hydroalkylation composition and process for producing said composition

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.

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.
