  1. 1.

    Ethylene oxide as well as acetaldehyde and a hydroperoxide are the reaction products of the ethyl radical and molecular oxygen at temperatures from 100° to 300°.

  2. 2.

    The direction of the reaction C2H5 + O2 is strongly affected by the state of the surface of the reaction vessel.

  3. 3.

    Formation of ethylene oxide in the reaction of the ethyl radical and a molecule of oxygen occurs on the walls of the reaction vessel that had been treated with the products from a discharge in water vapors.

  4. 4.

    The reaction of the ethyl radical with a molecule of oxygen does not lead to formation of formaldehyde at temperatures up to 300° either by a direct route or through intermediate reactions.
