Transition metal-substituted Keggin-type polyoxometalates as catalysts for adipic acid production
The adipic acid (AA) production was carried out in two stages: oxidation of cyclohexanone (-one) by Keggin-type polyoxometalate (POM), followed by oxidation of this latter by hydrogen peroxide. The process lasts 20?h and the temperature is maintained at 90?°C. AA is then recovered by cold crystallization (4?°C). The POMs have as formula HMPMo12O40 (M:Co, Ni, Mn, Cu or Zn). The materials were characterized by FT-IR and UV–Vis spectroscopies and by thermogravimetric analysis. The purity of adipic acid was confirmed by FT-IR and 13C and 1H NMR analysis. The effects of POM composition, catalyst/-one molar ratio and the cyclohexanol addition to -one on adipic acid yield were examined. The whole catalysts were found to be effective toward cyclohexanone oxidation and the highest yield (53%) was obtained with HZnPMo12O40 system for a catalyst/-one molar ratio of 1.89?×?10?3. The alcohol addition to -one has a negative effect on adipic acid formation.
