文摘A series of novel azo disperse dyes were synthesized by coupling reaction of 4-benzyloxyphenol with diazotized p-substituted aniline derivatives as diazo components. These compounds were characterized by spectroscopic techniques and elemental analysis. Ionization constants, pKa, for these dyes were determined using electronic spectroscopic method.
