Synthesis of Adipic Acid Using H₃PW₆Mo₆O₄₀/SiO₂ as Catalyst

Abstract:

A novel catalyst, H₃PW₆Mo₆O₄₀/SiO₂ was prepared by a sol-gel technique, and characterized by FT-IR and XRD. Using aqueous hydrogen peroxide solution (30wt%) as oxidant, sodium bisulfate (NaHSO₄) as acid ligand, adipic acid was synthesized with cyclohexanone as raw material and H₃PW₆Mo₆O₄₀/SiO₂ as catalyst. The factors influencing the synthesis were discussed and the best reaction conditions were found out. Experimental results showed that H₃PW₆Mo₆O₄₀/SiO₂ is an excellent catalyst. When n (cyclohexanone):n (H₂O₂) : n (H₃PW₆Mo₆O₄₀/SiO₂):n (NaHSO₄) = 100:440.7:0.21:0.74, reaction temperature is 90°C and reaction time is 6 h, the yield of adipic acid can reach 90.2%.
