  • Process for production of alcohols
    Patent number: 7235702
    Abstract: The invention disclosed relates to the production of alcohols. A first aspect of the invention relates to a process for production of alcohols, and in particular to a process for the catalytic hydration of an olefin to the corresponding alcohol in substantially anhydrous form, under selected mild reaction conditions, and using a selected catalyst. A second aspect of the invention relates to a process for dehydration of an azeotropic mixture, including a first alcohol and water. A hydration reaction between the water in the azeotropic mixture and an added olefin, under selected mild conditions, and using a selected catalyst, produces a product including a second alcohol corresponding to the olefin, and the first alcohol, in substantially anhydrous form.
    Type: Grant
