The activity of synthetic zeolites NaA and CaA, modified by cations of copper and palladium, was investigated in the reaction partial oxidation of butyl alcohol in the presence of molecular oxygen into butyric aldehyde. It was established, that the synthetic zeolite CaA, modified by positive ions of copper and palladium in amount 3wt % and 1wt%, accordingly, shows high activity in this reaction. The obtained results testify to perspective of using this catalyst in the reaction of  partial oxidation of butyl alcohol
