반응 단계
Benzidine sulfone used as the diamine component in the synthesis of the novel copolyamide is a known compound, and it can be prepared, for example, by a method comprising reacting biphenyl with sulfur in the presence of anhydrous aluminum chloride to form dibenzothiophene, oxidizing dibenzothiophene with hydrogen peroxide to form dibenzothiophene-5,5'-dioxide, nitrating the dioxide with concentrated nitric acid to form 3,7-dinitrodibenzothiophene-5,5'-dioxide and reducing the so formed dioxide with stannous chloride in the state acidified by hydrochloric acid to form benzidine sulfone.
