Abstract
Sodium dimethyldithiocarbamate, NaDTC, was electrochemically oxidized to tetramethylthiuram disulphide, TMT, in an univided electrolytic cell using a couple of rhutenized titanium electrodes; in earlier work the electrodes were platinum. The reaction was carried out in an emulsion formed by mixing saturated aqueous sodium chloride solution containing the substrate with a suitable organic solvent at constant current density. The product was obtained with a high yield and high degree of purity after the passage of the theoretical amount of charge. It was found that at a high current density and a high reactant concentration the product solubility in the organic solvent used determines the success of the electrochemical reaction. Possible reaction mechanisms are also discussed.
