Reaction under nitrogen atmosphere setup
WebThe net reaction in the catalytic cycle is: 2 O 2 + RCH 3 RCH 2 OH + O 3. The brown, nitrogen-centered radical NO 2 is in equilibrium with its colorless, diamagnetic dimer N 2 O 2. The N-N bond in the dimer is weak. Below is a picture of 2 tubes of the gas mixture at 25 deg. The same tubes were heated (100 deg) and cooled (0 deg).
