WebThat is then converted into nylon-6,6 by heating it under pressure at 350°C. The two monomers can both be made from cyclohexane. Oxidation of the cyclohexane opens the ring of carbon atoms and produces a -COOH group at each end. That gives you the hexanedioic acid. Some of that can then be converted into the 1,6-diaminohexane.
