ABSTRACT

The synthesis involves the diazotization of 2-amino-5-(2-sulfooxy) ethyl sulfonyl) benzene sulfonic acid followed by azo coupling in acidic medium with 2,4-diamino benzene sulfonic acid respectively for yellow dye (1c). Similar series of reaction were carried out for orange dye (1’c) which involves the diazotization of 2-amino-5-(2-sulfoxy) ethyl sulfonyl) benzene sulfonic acid) followed by azo coupling in acidic medium with 7-amino-4-hydroxy naphthalene-2-sulfonic acid respectively. Exhaust dyeing process for reactive dyes was performed which showed both the dyes were showing the highest shade in cotton followed by nylon, wool, acrylic, acetate & polyester. Keywords: Azo dye, Coupling reaction, Diazotization
