Process for the production of a catalyst for the hydration of olefins into alcohols

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 K2O,...

Zusammenfassung:	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 K2O, until the clay has an Al2O3 content of 13-18% by weight, thereby obtaining a surface area of 200-400 m2/g; (B) molding the clay at a total water content of 20-35%; (C) calcining at 500 DEG -800 DEG C.; (D) acid-treating the molded and calcined clay to an Al2O3content of 1-5% by weight, thereby obtaining a surface area of 150-250 m2/g; and (E) impregnating said material with phosphoric acid.
