Oxidation studies of carbohydrates using molecular oxygen and a bismuth-ruthenium oxide catalyst

The oxidation of trans-1,2-cyclohexanediol, methyl α-D-glucopyranoside and β-cyclodextrin has been studied, using a heterogeneous oxidation system in water at 50-75°C. Molecular oxygen at 15-20 bar was used as the oxidant, in combination with a bismuth-rich ruthenium pyrochlore oxide as the catalyst. Both oxidative cleavage of the vicinal diols and oxidation of the primary hydroxyl groups occurred. HPLC and 13C NMR were used to analyse the complex product mixtures. The oxidation method is successful for glycol cleavage in small carbohydrates but not for polysaccharides.
Optimization of a cyclohexanone distillation stage in the presence of alkali

experimental part, p. 1767 - 1771 (2012/02/05)
Kinetics of two reactions: hydrolysis of esters and condensation of cyclohexanone in an alkaline environment, was studied in model mixtures. Derived kinetic equations were used to assess optimal parameters of proceeding cyclohexanone distillation in the presence of alkali.
