ANALYSIS AND PREPARATION OF AZO DISPERSE DYE C33H36N6O5

Dyes are chemical compounds that can attach themselves to fabrics or surfaces to give them colour. Most dyes are complex organic molecules and need to be resistant to weather and the action of detergents. Dyes add color to textiles. They are incorporated into the fibre by chemical reaction, absorption or dispersion. Dyes differ in their resistance to sunlight, perspiration, washing, gas, alkalies, and other agents; their affinity for different fibres; their reaction to cleaning agents and methods and their solubility and method of application. In short, dyes are coloured, ionising, aromatic organic compounds1.In ancient past, Indigo, obtained from plants was being used by the Egyptians 5000 years ago, and natural dyes obtained from plants and animal sources are still used today. In 1856, Perkin developed the first synthetic dye based upon aniline. In this paper author prepared and analysis azo dye C33H36N6O5.
