Oxidation of Alcohol Component of Microemulsion by Lipophylic Cr(VI)

Abstract

The oxidation kinetics of butanol present in the microemulsion by CTADC (cetyltrimethylammonium dichromate) is studied using UV-Vis spectroscopic technique. The phase behaviour of mixture containg Surfactant(TX100)/ co-surfactant (butanol)/ oil (chloroform) and water in presence and absence of CTADC have been studied by visual titration method. The reaction is 1st order with respect to the oxidant CTADC. With increase in surfactant concentration and acid concentration rate of the reaction increases. With increase in n-Butanol concentration rate increases up to 15x10-2M and the order with respect to butanol is found to be 1. After 15x10-2M concentration of n-butanol rate decreases due to structural change in which the reactants CTADC, butanol and acetic acid are partitioned in to different domain of microemulsions.
