Abstract
A novel method to prepare a solid acid catalyst through the reaction of a metal-alkyl halide species and the surface hydroxyl group of a solid support is disclosed. Lewis acidic metals, e.g., B, Al and Ga, etc., can then be anchored on the surface via the formation of an oxygen-metal bond. The solids containing these metals can be used as catalysts that will catalyze organic compound coversion reactions, e.g., Friedel-Crafts type reactions, olefin oligomerization, aromatic alkylation and acylation, alkane alkylation and isomerization reactions.
Claims15
A method of preparing a catalyst composition consisting essentially of halides of a single metal component anchored on an adsorbent solid by an oxygen-metal bond which comprises contacting an adsorbent inorganic oxide support containing surface hydroxyl groups with organic metal halide, under conditions sufficient for said organic metal halide to react with at least a portion of said surface hydroxyl groups wherein said metal is aluminum, and said adsorbent inorganic oxide support is selected from the group consisting of silica, silica-alumina, clay, crystalline porous silicates, silicoaluminophosphates, titania, vanadia, and rare earth oxides.
