OXIDATION OF MENTHOL: REACTION-RATE DETERMINATION BASED ON THERMODYNAMIC PROFILES

This study investigated the reaction kinetics of menthol oxidation. For this purpose the thermal profiles obtained from the measurements within the reaction calorimeter were used for the first time. In our case the reaction was performed under isothermal conditions using potassium dichromate as a catalyst. Due to the low solubility of menthol in water, acetone was added to the diluted sulfuric acid as a co-solvent. This caused the reaction medium to become more homogeneous and thus more appropriate for kinetic analyses without considering a mass transfer term.
