SYNTHESIS OF ADIPIC ACID FROM CYCLOHEXANOL

Introduction:

Adipic acid is a white crystalline solid used primarily in the manufacture of nylon 6, 6 polymers for fibers and plastics. In this experiment, adipic acid was synthesized in two steps starting from cyclohexanol. Cyclohexanol was first oxidized to cyclohexanone using sodium hypochlorite. The intermediate product cyclohexanone was then further oxidized to adipic acid using hot potassium permanganate. Both steps were oxidation reactions.

Main reactions:

RXN-1: Preparation of cyclohexanone

RXN-2: Preparation of Adipic Acid
