Title compds. (T; Z = H, CH3, OCH3, SO3H or COOH; Y = H, CH3, C2H5 or OCH3; n = 0 or 1; H2O3P-(CH2)n- is positioned at meta or para about azo group) were manufd. by reaction of aminoazo compd. (II) and sulfonating agent. Thus, diazotated 3-amino-4-sulfurbenzenphosphonic acid was coupled with 3-methylaniline to give 4-amino-6-methyl-6'-sulfur-1,1'-azobenzene-3'-phosphonic acid, which was mixed with sulfuric acid and sodiumchloride to give 4-amino-6-methyl-3,6'-disulfur -1,1'-azobenzene-3'-phosphonic acid.
