Abstract:

Using aqueous hydrogen peroxide solution (30wt%) as oxidant, potassium bisulfate (KHSO4) as acid ligand, adipic acid was synthesized with cyclohexanone as raw material and H4SiW6Mo6O40/SiO2 as catalyst. The factors influencing the synthesis were discussed and the best reaction conditions were found out. Experimental results showed that H4SiW6Mo6O40/SiO2 is an excellent catalyst. The optimal conditions are: n (cyclohexanone):n (H2O2)=1:4.0,catalyst dosage is 0.4g, mass of acidic ligands is 0.1g, and the reaction time is 4 h, the yield of adipic acid can reach 93.7 %.
