The sodium, boron, calcium, magnesium, zinc, aluminum, and zirconium salts of 12-tungstophosphoric acid have been prepared and characterized using x-ray diffraction, mercury porosimetry, the chemisorption of ammonia, and Hammett indicators. Methanol conversion at 350/sup 0/C and a variety of residence times produced hydrocarbons ranging from C/sub 1/ to C/sub 5/ in amounts which varied with the cation. The more strongly acidic salts produced the higher yields of hydrocarbons. The maximum yield of the major product C/sub 4/ was found with the aluminum salt. The activities were related to the partial change on the oxygen atoms in the various catalysts. 3 figures, 1 table.
