Alkylation of aromatics with propylene and higher olefins

摘要

An aromatic hydrocarbon is alkylated with an alpha olefin containing three to 10 carbon atoms, or more, by intimately contacting the alpha olefin and the aromatic hydrocarbon with a catalyst produced by contacting (a) a refractory metal oxide/silica support such as alumina/silica wherein the silica content of the support is from two to 95 weight percent and the metal oxide content of the support is from five to 98 percent with (b) a tris(cyclopentadienyl)trinickel dicarbonyl. This process results in the production of significant quantities of alkylated aromatic hydrocarbons.
