    BACKGROUND REPORT AP-42 SECTION 6

    Adipic acid is manufactured from cyclohexane in two major reactions. The first step, shown in Figure 2.2-A, is the oxidation of cyclohexane to produce cyclohexanone (a ketone) and cyclohexanol (an alcohol). This ketone-alcohol (KA) mixture is then converted to adipic acid by oxidation with nitric acid in the second reaction, as shown in Figure 2.2-B.
