【Abstract】 The catalysts of synthesizing phthalic anhydride from naphthaleng,n pentane or o xylene are introduced.These catalysts include the catalyst based on vanadium pentoxide,molybdenum dioxide catalyst, vanadium pentoxide titania kali salt catalyst and VPO catalyst.Influence of each component on the catalysts is discussed.Idea to delevop new type of cataltst is proposed.The studying institution and producing factory of catalysts should combine with producing factory of phthalic anhydride to develop new catalysts in the place of imports.更多还原
