Abstract
Aqueous acidic solutions of certain thallium(III) organosulfonate having at least 0.1 molar thallium ion concentration are contacted with an organic compound to form a related oxidized organic compound. The oxidized compound is separated and recovered from the solution and the resultant thallium(I) rich solution is electrochemically treated to regenerate thallium(III) which, in turn, can be reused in a cyclical process. The present invention provides a highly effective means of oxidizing organic substrates.
