Conclusions

  1. 1.

    It was determined by IR spectroscopy that the catalytic properties of PdCuNaY zeolite in the oxidation of ethylene to acetaldehyde are determined by the amount of water in the zeolite: With a water content of up to 15%, only traces of acetaldehyde are formed, and an increase in the water content (up to 40–44%) causes an increase in the activity of the catalyst.

  2. 2.

    The role of water in the catalysis of ethylene oxidation on PdCuNaY was discussed on the basis of an assumption of the similarity of mechanisms of homogeneous and heterogeneous oxidation of olefins to carbonyl compounds and of the properties of hydrated Y-type zeolites containing palladium and copper cations.
