Oxidation of Distyryl Ketone by Quinaldinium Chlorochromate – A Kinetic Study

Abstract

Oxidation of distyryl ketone by quinaldinium chlorochromate [QnCC] in water and acetic acid medium has been studied under pseudo-first order condition. The reaction shows unit order dependence, each with respect to oxidant and hydrogen ion. The reaction with respect to substrate is found to be fractional order. The reaction rate decreases with increasing the concentration of Mn2+ ions. The reaction does not induce the polymerization of acrylonitrile. A possible mechanism has been proposed in the formation of cinnamic acid and Phenyl acetaldehyde.
