Synthesis of some azo disperse dyes by the use of focused microwave heating

The synthesis of new azo disperse dyes by healing of diazoaminobenzene with active methylene compouds under focused microwave heating in acetic acid solution, in the presence of few drops of hydrochloric acid were described. The dyeing of polyester fabrics with disperse dyes by using of high temperature dyeing method a: 130°C and carrier dyeing method were also used. In order to ascertain the relation between the dyeing properties of polyester fabrics and dye uptake, the fastness properties of dyed fabrics such as light, washing, perspiration and rubbing were measured.
