Study of Monoazo Acid Dyes Based on Phenol System and their Application

3- [ (2-methyl-6-Chloro-4- quinolinyl) amino] phenol (II) used as a coupling component was prepared by the condensation of 2-methyl-4, 6-dichloroquinoline1 (I) and 3- aminophenol. Fourteen Acid dyes (III a-n) were prepared by coupling (II) with various diazo component (R a n). These dyes were applied on silk, wool and nylon fabrics. The study of exhaustion and the absorbance at specific max ( nm) of acid dyes, their application on various fabrics.
