DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 22 Contact glow discharge electrolysis (CGDE) of alkanesulfonates in a neutral phosphate buffer soln. was studied. Methanesulfonic acid was oxidatively degraded to inorg. C and sulfate ion as the final products. Also in CGDE of ethanesulfonate and 1-propanesulfonate, the oxidn. of alkyl and sulfo groups smoothly proceeded and various carboxylic acids such as oxalate and formate are the intermediate products. From product distribution and kinetic studies, it was assumed that hydroxyl radicals would play a crucial role in the oxidative degrdn. of aq. alkanesulfonates. .
