Abstract:
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.
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:
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.
Abstract:
Catalysts active for the olefin reaction, including olefin disproportionation are provided comprising molybdenum or tungsten oxides associated with a suitable support material which has been subjected to treatment at high temperature in combination with organoaluminum compounds. The supported molybdenum or tungsten oxide can optionally be contacted with nitric oxide, nitrosyl halide, and alkali or alkaline earth metal compounds prior to treatment with the organoaluminum compound.
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:
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.
Abstract:
An aromatic hydrocarbon is contacted under hydroalkylation conditions and in the presence of hydrogen with a composition comprising at least one ruthenium compound impregnated on a calcined, acidic, nickel and rare earth-treated crystalline zeolite support.
Abstract:
Olefins, or mixtures of various olefins, are converted to other olefins by contact with a supported molybdenum oxide or tungsten oxide organoaluminum catalyst.
Abstract:
An aromatic hydrocarbon is contacted under suitable hydroalkylation conditions with a composition comprising a calcined, acidic, nickel and rare earth-treated crystalline zeolite.
