    摘要: A method for purification of acetone containing at least one oxidizable impurity. The method comprises the steps of: (a) contacting acetone containing at least one oxidizable impurity with a heterogeneous oxidation catalyst in the presence of oxygen for a time and at a temperature sufficient to oxidize at least a portion of at least one of the oxidizable impurities; and (b) substantially separating purified acetone from the resulting mixture obtained from step (a).
