Abstract

SYNTHESIS, CHARACTERISATION AND APPLICATION PROPERTIES OF SOME NOVEL ACID AZO DYES.

Dr. D.G.Patel and N.K.Prajapati*

ABSTRACT

Novel acid azo dyes have been prepared by the coupling of diazo solution of 4 –methyl Aniline with 1-(4-N-acetyl amino) 2-methyl phenyl, 2-chloro ethanone. The resultant product were hydrolysis by refluxing with ethanol containing for 4-5 hours. The coupling compound of various aromatic acid 1a-1g with above diazonium salt soln. The resultant 2a-2g dyes were characterized by spectral techniques, i.e., elemental analysis, IR, UV––visible spectroscopy. The dyeing performance of all the dyes was evaluated on wool and nylon fabrics and studies their light and washing fastness properties.
