【Abstract】 The selective oxidation of propene by heteropolyacid catalysts with Keggin structure was studied. Results showed that Cu, V, and As can improve the yields of the target product AA, and the highest yield (23%) was obtained over catalyst with composition of H\|Cu\-\{0.2\}\|Cr\|P\|Mo\-\{12\}\|As\-\{0.6\}\|O at 360 ℃, space velocity of 850 h\+\{-1\}, and O\-2∶C\-3\+==4∶1.更多还原
