Özet

5-amino-4-arylazo-3-methyl-1-phenylpyrazoles (2a-k)were diazotised and coupledwith 5-hydroxy-3-methyl-1H-pyrazole and 5-hydroxy-3-methyl-1-phenylpyrazole to generate two series disazo pyrazole disperse dyes (3a-k and 4a-k). These novel synthesized disazo pyrazole disperse dyes were characterized by elemental analysis and spectral methods. Absorption ability and tautomeric structure of synthesized disazo pyrazole disperse dyes substituted with electron-withdrawing and electron-donating groups at their o, m- and p-positions were also examined in detail.
