Abstract

FORMATION OF SOME NOVEL ACID AZO DYES: SYNTHESIS CHARACTERISATION AND APPLICATION PROPERTIES:II

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

ABSTRACT

Novel acid azo dyes were prepared by the coupling of diazo solutions of 4-Chloroaniline with 1-(4-N-acetyl amino) 2-methyl phenyl - 2- chloro ethanone. Then resultant product were hydrolysis by refluxing with ethanol containing HCl for 4-5 hours. The coupling compound of various aromatic acid R1-R6 with above diazonium salt solution. The resultant dyes were characterized by elemental analyses as well as IR spectral studies. The UV-visible spectral data have also been discussed in terms of structural property relationship. The dyeing assessment of all the dyes was evaluated on wool and polyester textile fibers.

Keywords: Acid azodye, diazonium salt, UV––visible spectroscopy ,
