Abstract

The kinetics of the oxidation of dibenzalacetone (DBA) by isonicotinium dichromate (INDC), in acetic acid medium, catalysed by 1,10-phenonthroline has been investigated. The reaction shows fractional order dependence with respect to [H+], 1, 10-phenanthroline and first order dependence with respect to [oxidant] and [substrate]. The reactions are carried out for various substituents at different Concentration and at four different temperatures. Activation parameters have been calculated and a suitable mechanism has been proposed.
