Chromic acid oxidation of 2-butanol to 2-butanone has been carried out by using three representative promoters: picolinic acid, quinolinic acid (2,3 PDA), and dipicolinic acid (2,6 PDA) in the presence and absence of surfactants (SDS, CPC, TX-100). Various combinations have been studied to select the most suitable combination of promoter and micellar catalyst for this oxidation. Reactions were done under kinetic condition [2-butanol]T ≫ [Cr(VI)]T in aqueous media at room temperature. The pseudo-first-order rate constant k obs and half-life of all the reactions were determined. Based on the kinetic results, the combination of SDS and 2,3 PDA was found to be the most efficient for this oxidation. The mechanisms of both unpromoted and promoted reaction paths have been proposed. The product is confirmed by 2,4-DNP test, I.R., and 1H NMR spectroscopy. The anionic surfactant sodium dodecyl sulphate (SDS) accelerates the rate whereas no appreciable change in rate was observed in case of cationic surfactants, CPC, and neutral surfactants, TX-100.
