Method for preparing aldehyde ketone by catalyzing and oxidizing alcohol in air

This invention relates to a preparation method for aldehydes and ketones by catalytic airy oxidation of alcohols. In this invention, supported nano-scale RuO2 with a mass fraction of 2.5~12% is adopted as catalysts and one of the ZSM-5, MCM-41 and SBA-1 is adopted as catalyst carrier. The whole reaction is kept at 60~100 deg.C for 4~48 hours in the presence of reactive solvents so as to produce aldehydes or ketones by catalytic oxidation. In this invention, an extremely high conversion efficiency and selectivity towards aldehydes and ketones can be achieved; the reaction can be accomplished in one step; and the process is quite simple. Compared to conventional oxidants, air as the oxidant is much cheaper and more friendly to the environment.
