Electrochemical chlorination of non-saturated organic compounds in the aqueous and non-aqueous solvents depends on the mechanism of halogen formation. The mechanism of chloride ion discharge has been investigated in nitromethane on the rotating Pt disc electrode using Ag/AgClO₄ system in the galvanostatic measurement as the reference electrode. For the quasi-equilibrium process the constant k₂ and the constant of electron K₂ transmission have been determined for the recombination process occuring at 0.1 V.
The photoelectrical proparti«« of the rotating Cu diac electrode have been lnveatigated. It has been polarized anodically in 652 orto-H₃PO₄. Presence of the oxide layer on the electrode surface has been stated. The layer has n - semiconductor properties at high values of anodic potential of polarization.
