Catalytic oxidation kinetics of sugar and sugar alcohols with different oxidants has been given a great deal of attention in past years. In continuation of our earlier work, we report here in the Catalytic oxidation kinetics of sugar and sugar alcohols with different oxidants in acidic medium. It has been utilized as effective oxidant for the oxidation of various functional groups in last few decades. The kinetics and mechanism of oxidation of sugars and sugar alcohols have been studied in acidic media employing different transition metal ions, inorganic acids, complex ions and hydrogen peroxide as oxidants. Both oxidations occur under different conditions of pH, temperature and ionic strength giving products that depend on the oxidants used. The results showed that the mechanism may depend on the nature of the substrates; in some cases it involves the formation of intermediate complex, free radical or transition states. The current review summarizes selective research on Kinetics determination of sugar and sugar alcohols in acidic medium.
