The reaction of 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM][BF4]) with potassium permanganate has been studied in aqueous solution. The oxidation proceeds through at least two stable organic intermediates which have been isolated and completely characterized. They are: 1-ethyl-3-methyl-2,4,5-trioxoimidazolidine and N-ethyl, N'-methylethanediamide. Kinetic studies of this degradation process will also be discussed.
