Voltammetric Studies at Glassy Carbon Electrodes in Sulfuryl Chloride Solutions
Abstract
The electrochemical reduction and oxidation of sulfuryl chloride in 1M LiAlCl4-SO2Cl2 solutions were studied at glassy carbon electrodes using the technique of cyclic voltammetry. It was found that the reduction of chlorine, which is formed by the decomposition of sulfuryl chloride, precedes and obscures the reduction of sulfuryl chloride. Thus, in chlorine-rich solutions, sulfuryl chloride reduction peak in the cyclic voltammograms is completely masked by the chlorine reduction peak. However, in solutions saturated with sulfur dioxide, the chlorine reduction peak is relatively smaller than teh sulfuryl chloride reduction peak. The reduction of both chlorine and sulfuryl chloride leads to the deposition of insoluble lithium chloride at the electrode surface and results in its passivation. The elctrochemical oxidation of LiAlCl4-SO2Cl2 solutions leads to the formation of chlorine, first by the oxidation of AlCl4- ions followed by the oxidation of sulfuryl chloride.
