Author(s): A Palanivel, P Rajkumar and K Subramani
Abstract: The oxidation of α-hydroxy acids by Isoquinolinium Fluorochromate (IQFC) has been studied in micellar medium. The oxidation of free α-hydroxy acids was also carried out under the same conditions for comparative purpose. The reaction was followed by observing the decrease in the absorbance at 501nm for the Cr (VI) present in the reagent in a UV-Visible spectrophotometer. The rate of oxidation of α-hydroxy acids are enhanced more in the presence of non-ionic micelle of Polysorbate 80, when compared to the anionic micelle of Sodium lauryl Ether Sulphate (NaLES) and cationic micelle of Benzethonium Chloride (BTCl). Product and stoichiometric analysis were carried out for the oxidation of complexes and free ligands. A mechanism involving two electron transfers for the ligand was proposed.
