Abstract
Conversion, e.g. dehydration, of aliphatic organic oxygenates having up to about 6 carbon atoms by contact with a crystalline aluminosilicate zeolite, preferably ZSM-5, having a silica to alumina ratio substantially greater than 10, at a temperature of about 70.degree. to 1400.degree. F, depending upon the exact nature of the reactant and product.
Claims2
In the process of dehydrating an alcohol, by contacting it at a temperature of about 70.degree. to 1400.degree. F with a solid crystalline aluminosilicate zeolite acidic catalyst having a pore size sufficient to permit the diffusion of said alcohol thereinto and to permit dehydration therein, the improvement whereby carrying out said dehydration with exceptional catalyst stability, which comprises utilizing said zeolite having a silica to alumina ratio substantially greater than 10 to 1.
