A METHOD OF PRODUCING A CATALYST FOR HYDRATION OF OLEFINS TO ALCOHOLS COMPRISING THE STEPS OF PRELIMINARY TREATMENT OF A POROUS SILICEOUS MATERIAL SELECTED FROM THE GROUP OF DIATOMITE, KIESELGUHR, AND DIATOMACEOUS EARTH, WITH A HOT AQUEOUS SOLUTION OF AN INORGNIC ACID AT TEMPERATURE RANGING FROM ABOUT 40*C. TO THE BOILING POINT OF SAID SOLUTION FOR SEVERAL HOURS AND WASHING THE RESULTANT MATERIAL WITH WATER, PREPARING A PASTE BY MIXING SAID TREATMENT SILCEOUS MATERIAL WITH BENTONITE CLAY ADDED IN AMOUNTS OF 1 TO 10% OF THE TOTAL DRY WEIGHT OF THE MIXTURE, AND TITANIUM DIOXIDE ADDED IN AMOUNTS OF 1 TO 10% OF THE TOTAL DRY WEIGHT OF THE MIXTURE, MOLDING SAID PASTE, CALCINING THE RESULTING MOLDED CARRIER AT TEMPERATURES RANGING FROM 1050 TO 1350*C., AND SATURATING SAID CALCINED CARRIER WITH A SOLUTION OF PHOSPHORIC ACID.
