Abstract:
The kinetics of one-pot oxidative hydrolysis of cellulose, arabino-galactan and xylan were studied in the presence P-Mo-V heteropoly acids as catalysts. The main reaction products fro all substrates appeared to be formic acid and formaldehyde. The observed results allowed us to suppose that one-pot oxidative-hydrolysis in the presence of P-Mo-V heteropoly acids proceeded by a mechanism similar to the periodate oxidation. Vanadium species can connect to hydroxide groups of sugars and broke C-C bond to give formic acid and shorted sugar. Finally such oxidation of C6-aldose leads to formation of 5 molecules of formic acid a 1 formaldehyde molecule. Moreover connection of vanadium to polysaccharides molecules facilitating hydrolysis is also possible.
