Patent number: 5962760Abstract: A process for the alkylation of aromatic compounds with an olefin or alkyl halide having from 1 to 24 carbon atoms utilizes a novel catalyst comprising: a) a refractory inorganic oxide, b) the reaction product of a first metal halide and bound surface hydroxyl groups of the refractory inorganic oxide, c) a second metal cation, and d) optionally a zerovalent third metal. The refractory inorganic oxide is selected from the group consisting of alumina, titania, zirconia, chromia, silica, boria, silica-alumina, and combinations thereof and the first metal halide is a fluoride, chloride, or bromide of aluminum, gallium, zirconium, or boron. The second metal cation is selected from the group consisting of: monovalent metal cations in an amount from 0.0026 up to about 0.20 gram atoms per 100 grams refractory inorganic oxide for lithium, potassium, cerium, rubidium, silver, and copper, and from 0.012 to about 0.20 gram atoms for sodium; and alkaline earth metal cations in an amount from about 0.0013 up to about 0.Type: GrantFiled: August 4, 1997Date of Patent: October 5, 1999Assignee: UOP LLCInventors: Joseph A. Kocal, Anil R. Oroskar

Patent number: 5132478Abstract: Aromatic compounds are alkylated with C.sub.20 -C.sub.1300 olefinic oligomers using an acidic alkylation catalyst to produce alkylated aromatic products, usually alkylaromatic hydrocarbons. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with reduced metal oxide catalyst, preferably reduced chromium oxide on a silica support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. If the alkylation is carried out under certain combinations of conditions, especially using a Lewis acid catalysts such as aluminum trichloride and at higher temperatures, the alkyl portion of the product will undergo isomerization. The alkylaromatic compositions show improved thermal stability and are useful as lubricant basestocks and additives for improved antiwear properties, antioxidant and other properties.Type: GrantFiled: December 19, 1990Date of Patent: July 21, 1992Assignee: Mobil Oil CorporationInventors: Suzzy C. Ho, Margaret M. Wu
