摘　　要：The adsorbed state of propylene oxide on MgO,ZnO and Al2O3were studied by IR spectroscopy.The IR results of PO adsorbed on MgO showed the appearance of 3 080 cm-1and 1 644 cm-1characteristic adsorption bands,which attribute to alkylene species,and the epoxide ring of propylene oxide was preferentially opened at O-C（1） bond.PO adsorbed on Al2O3showed the appearance of 1106cm-1peaks,which attribute to C-O stretching vibration,and the epoxide ring was preferentially opened at O-C（2） bond.The adsorbed species formed on MgO and Al2O3had the stability to some extent.The results of PO adsorbed on ZnO showed no chemical absorption occuring on ZnO suface.The adsorbed state of propylene oxide on MgO, ZnO and Al2O3 were studied by IR spectroscopy. The IR results of PO adsorbed on MgO showed the appearance of 3 080 cm^-1 and 1 644 cm^-1 characteristic adsorption bands, which attribute to alkylene species, and the epoxide ring of propylene oxide was preferentially opened at O- C（ 1 ） bond. PO adsorbed on Al2O3 showed the appearance of 1106cm^-1 peaks, which attribute to C-O stretching vibration, and the epoxide ring was preferentially opened at 0-C（2） bond. The adsorbed species formed on MgO and Al2O3 had the stability to some extent. The results of PO adsorbed on ZnO showed no chemical absorption occuring on ZnO suface.
