Reactivity Of Some Hydroxy Acids By Benzimdazolium Fluorochromate

Abstract

Oxo acids are produced when Benzimidazolium fluorochromate (BIFC) oxidizes glycollic, lactic, and malic acids in dimethylsulphoxide (DMSO). In BIFC, the reaction is first order.   Kinetics of the Michaelies-Menten type are seen in relation to the hydroxyacids. Acrylonitrile cannot be made to polymerize through reaction. Hydrogen ions act as a catalyst for the reaction. The dependence on hydrogen ions is expressed as k_obs = a + b [H⁺]. Nineteen distinct organic solvents have been used to study the oxidation of lactic acid. The multiparametric equations by Kamlet and Swain have been used to analyze the solvent effect. A slow-step decomposition mechanism involving the formation of oxoacids has been proposed.
