摘要：
MeAlPO-5, MeAPSO-35, MeAlPO-18 and MeAPSO-18(Me=Co, Mn) were prepared by hydrothermal synthesis and were characterized by XRD and TPD(NH3). Their catalytic properties for the oxidation of octane were studied by using oxygen as the oxidant. In the oxidative products, there were octanones, octanols, cracked oxygenates and oxygenates with more than one functional group. The selectivity over different catalysts was similar. The ratio of n(octanone)/n(octanol) on MeAPSO was higher than that over the same type MeAlPO molecular sieve. The experiment of catalyst removal showed the oxidation was a heterogeneous reaction. Moreover, the effects of reaction time and temperature on the oxidation were also investigated. According to the results, we discussed the reaction mechanism.
