Abstract
Process of carrying out oxidation-reduction reactions such as oxidation of hydrogen sulfide to sulfur, in which a polyvalent metal chelate with a certain class of polycarboxylic acid is employed, the metal being reduced from a higher valence state to a lower valence state during reduction and back to the higher valence state by oxidation. The class of polycarboxylic acids are those which have a substituent which enhances acidity yet is stable toward oxidation.
