  • Hexanitrotetrachloroazobenzene and method of preparation
    Patent number: 4751289
    Abstract: 2,4,6,2',4',6'-Hexanitro-3,5,3',5'-tetrachloroazobenzene, a new, high melting explosive is prepared by the simultaneous nitration and oxidation of 3,5-dichloroaniline in strong or fuming sulfuric acid using fuming nitric acid or potassium nitrate as both oxidizing and nitrating agent. Under these conditions nitric acid or potassium nitrate is expected to be a nitrating agent only, and oxidation of the amino group is not expected.
