| 摘要 |
New N-4-aminophenyl-N'- 2,4-diaminophenyl- alkylene diamines of formula (I) and water soluble salts are claimed. In (I), R1 = -CnH2n- or -CH2-CH(OH)-CH2-; and n = 2-4. N-4-Aminophenyl-N' -2,4-diaminophenyl -ethylene diamine (IV) is claimed. (I) are prepd. by reacting N-(p-nitrophenylalkylene diamines of formula (i) with 2,4-dinitrofluorobenzene, to give N-4-nitrophenyl-N'- 2,4-dinitrophenyl- alkylene diamines (II), and catalytically hydrogenating (II).
