Vidya, V. G. published the artcileSynthesis, characterization and applications of some azo dyes derived from various aromatic amines, Quality Control of 116-63-2, the publication is Asian Journal of Chemistry (2018), 30(9), 2049-2053, database is CAplus.
In this work, we report the synthesis of metal free dyes and their fastness properties. A series of monoazo dyes were obtained by diazotization of various aromatic primary amines and coupling with different components. One colored Schiff base derived from triethylenetetramine and N,N-dimethyl-4-aminobenzaldehyde was also synthesized. These colored compounds were characterized by FTIR, UV-visible, 1H, 13C NMR and ESI mass spectroscopic methods. The dyeing performance of all the compounds were evaluated on cotton fabric. They were applied on bleached cotton fabric and their dyeing and fastness properties were assessed. The absorption spectra of the dyes are discussed with regard to their structure. The structure of colored dyes and Schiff base are proposed based on various spectroscopic data. The newly synthesized group of monoazo dyes gives shades ranging from yellow to reddish orange with good light fastness and excellent wash fastness.
