Abstract
A method for producing a carrier for a catalyst comprising the steps of mixing solutions of a soluble salt of aluminum and a soluble salt of silicic acid in a ratio that gives a precipitate comprising aluminum silicate having a weight ratio of Al.sub.2 O.sub.3 :SiO.sub.2 of 1:5 to 1:7, forming the precipitate into a carrier body, consolidating the carrier body by heating, and contacting the carrier body with an acid to reduce the Al.sub.2 O.sub.3 content to 1-5%. Thus produced carrier bodies are useful for catalyzing the hydration of olefins to alcohols when impregnated with phosphoric acid.
