Abstract

Oxidation of 4-oxo-4-phenyl butanoic acid by tripropylammonium fluoro chromate in the presence of picolinic acid-A kinetic and mechanistic study

Author(s): A. Yogananth and S. Sheik Mansoor

The oxidation of 4-oxo-4-phenyl butanoic acid (4-oxo acid) by tripropylammonium fluorochromate (TriPAFC) resulted in the formation of benzoic acid. The catalytic activity of picolinic acid (PA) has been studied in 50% acetic acid – 50 % water medium. The reaction is first order each in [TriPAFC], [4-oxo acid] and [H+]. The reaction rates were determined at different temperatures and the activation parameters computed. From the results, a suitable mechanism has been proposed.
