COUNTERACTION EFFECTS ON SURFACE AND CATALYTIC PROPERTIES OF 12-TUNGSTOPHOSPHATES

Some salts of tungstophosphoric acid (cesium, zinc and silver) were em ployed to determine their surface and catalytic properties. Except ces ium salt the other salts have surface area < 10 m2/g and possess littl e group of narrow pores with the existence of mesopores. Cesium salt ( 300-degrees-C) have shown to possess microporosity character with litt le group of mesopores and surface area > 120 m2/g. In conversion of 2- propanol (50-300-degrees-C) the dehydration reaction is more favourabl e than the dehydrogenation one.
