Abstract
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 DEG to 1400 DEG F., depending upon the exact nature of the reactant and product.
