Abstract

The PTA catalyzed oxidation of Citric acid by a mild and selective oxidizing agent N-chloroisonicotinamide (NCIN) leads to the formation of corresponding Acetone di carboxylic acid. The reaction carried out at 298K temperature. The reaction found first order in NCIN. The reaction follows Arrhenius relationship with respect to Citric acids. A retarding effect of acetic acid is observed. Various thermodynamic parameters have been computed. No evidence of polymerization of acrylonitrile showed no effect of free radical on the rate of reaction. Stoichiometric study revealed 1:1 mole ratio. On the basis of thermodynamic parameters and stoichiometry a feasible mechanism has been proposed and rate law has been derived.
