Diphenyl (4′-aminobiphenyl-4-ylamino)(pyridin-3-yl)methylphosphonate(1)was synthesized in 88% yield from reaction of pyridine-3-carboxaldehyde with benzidine and triphenylphosphite in the presence of titanium tetrachloride as a catalyst. Diazotization of1gave the corresponding diazonium salt2which was coupled with several hydroxyl or amino compounds to give the corresponding azo dyes3–8in 82–88% yields after crystallization. The dyes produced were applied to polyesters as disperse dyes and their fastness properties were elevated.

Various diazotized aryl amines were coupled with N-(4-nitrophenyl)-2-[(4-phenyl-1,3-thiazol-2-yl)amino]acetamide to give the corresponding various azo disperse dyes (D1-D13). These dyes were applied to polyester fiber by HTHP method and their fastness properties were evaluated. Dyes were characterized by IR, elemental analysis, and NMR spectral studies. These dyes showed very good antibacterial and antifungal activities.

In this paper synthesis of some new mono azo disperse dyes based on 2-amino 5-(4'-nitro phenyl) 1,3,4-thiadiazole moiety has been reported. Preparation of mono azo disperse dyes via condensation and nally diazotization of substituted primary amine and condensed with N-(4-(4'-chlorophenyl)thiazol-2-yl)-2-((5-(4'-nitrophenyl)-1,3,4-thiadiazol-2-yl)amino)acetamide (RR) to 1 give a series of mono azo dyes (RR -RR ). All the dyes were characterized by IR, H NMR, UV-Visible and elemental analysis and their dyeing 1 15 performance evaluated using High Temperature High Pressure method (HTHP) at 130°C on polyester fabric. All dyes gave good to excellent fastness properties.

Azo Disperse Dyes

Six new bis-azo disperse dyes were synthesized by linking various aryl amino and hydroxyl derivatives to 4-methoxy-2-nitroaniline and 6-amino-2,4-dihydroxypyrimidine moieties through diazo coupling reactions. The structures of the bis-azo dyes were identified by Fourier transform infrared, proton and carbon 13 nuclear magnetic resonance data. The prepared dyestuffs were applied onto polyester and nylon 6 fabrics and subsequently their fastness properties in terms of light, washing, sublimation and rubbing were determined. Compared with the light fastness of polyester fabrics, the light fastness of the dyed nylon 6 fabrics were slightly lower. The technical performance of the dyes on the two textile substrates used for the study, demonstrated their useful applications in the dyeing of synthetic fibres.
