Abstract
A process for producing a clay-containing catalyst for the hydration of olefins having 2-3 carbon atoms into alcohols, which comprises: (A) acid-treating a montmorillonite-containing clay which is contaminated by not more than 3% of quartz, feldspar or mica, and which may contain up to 0.5% of K.sub.2 O, until the clay has an Al.sub.2 O.sub.3 content of 13-18% by weight, thereby obtaining a surface area of 200-400 m.sup.2 /g; (B) molding the clay at a total water content of 20-35%; (C) calcining at 500.degree.-800.degree. C.; (D) acid-treating the molded and calcined clay to an Al.sub.2 O.sub.3 content of 1-5% by weight, thereby obtaining a surface area of 150-250 m.sup.2 /g; and (E) impregnating said material with phosphoric acid.
