Title: Synthesis of adipic acid via one-step oxidization of cyclohexene
Abstract: Synthesis of adipic acid from cyclohexene was investigated using 35% hydrogen peroxide as the oxidant and compound quaternary ammonium phosphotungstates as the catalyst. The catalyst could be separated from the reaction system after reaction and repeatedly used. Effects of the dosage of the catalyst, hydrogen peroxide and cyclohexene,reaction time and temperature were studied. The results indicated that the yield and purity of adipic acid of 85.0% and 99.6%, and the catalyst recovery of 88% were attained, respectively, under the reaction condition as follows : reaction temperature 95℃, reaction time 6h,cyclohexene dosage 8.2 g,35% H_2O_2 amount 42.7g and catalyst dosage 1.33g. The yield of adipic acid of 84.1% was still obtained after the catalyst system was repeatedly used 5 times.
