摘要：

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