Improvement in Preparation of Adipic Acid in the Laboratory

Lü Jian

Abstract

The concentrated phosphoric acid has been used as catalyst and hydrogen peroxide as oxidant to oxidize cyclohexanol to adipic acid.The effects of reaction condition were investigated.The experimental results indicated that the optimum condition was as follows: n(cyclohexanol) ∶n(hydrogen peroxide) ∶n(Phosphoric Acid) = 1∶3.5∶4.6,reaction time for 80 min,reaction temperature 95℃,the yield adipic acid of was 80.2%.
