摘要 In this study,self-prepared CHP is used as oxidant,nano-CuO as catalyst.The morphology and size of sample was characterized by XRD and SEM.The size of nano-CuO was much smaller than analytical grade CuO.Since the CHP can be prepared as reported over nano-CuO,we try to use air to oxidize cumene to obtain CHP and to oxidize styrene as soon as CHP was formed.After 12h reaction,the yield of benzaldehyde reaches 41.3%.The benzaldehyde obtained by oxidizing styrene over nano-CuO as the catalyst does not contain chlorine impurity and can be used in food industry. In this study, self-prepared CHP is used as oxidant, nano-CuO as catalyst. The morphology and size of sample was characterized by XRD and SEM. The size of nano-CuO was much smaller than analytical grade CuO. Since the CHP can be prepared as reported over nano-CuO , we try to use air to oxidize cumene to obtain CHP and to oxidize styrene as soon as CHP was formed. After 12h reaction, the yield of benzaldehyde reaches 41.3%. The benzaldehyde obtained by oxidizing styrene over nano-CuO as the catalyst does not contain chlorine impurity and can be used in food industry.
