Synthesis of 4,4-Diaminodiphenylamine sulphate: It could be obtained by the materials of nitrochlorobenzene o-amino acid and acetanilide. First step, make the nitrochlorobenzene o-sulfonic acid into sodium. After condensation with p-amino acetanilide, please use the iron to reduce. Second step, adding sodium carbonate with sulfuric acid, after hydrolysis, salt formation, filtration and drying, you can get the product.
