Kinetics and Mechanism of Oxidation of Thiodiglycollic Acid by Quinolinium Fluorochromate and Quinolinium Chlorochromate.

Abstract

Kinetics of oxidation of thiodiglycollic acid (TDA) by quinolinium fluorochromate (QFC) and quinolinium chlorochromate (QCC) have been studied in aquo-acetic acid media under varying conditions. In both the cases of study the order of the reaction is found to be one each with respect to oxidant and substrate. The rates increase with the increase in acetic acid composition of the solvent and with increase of [H⁺]. The reaction did not induce polymerisation of acrylonitrile and addition of Mn(II) decreased the rate considerably. On the basis of the results, a suitable mechanism has been proposed.
