In an Erlenmeyer (250 ml), 7 g (0.0

In an Erlenmeyer (250 ml), 7 g (0.02 mol) of p-nitroaniline was dissolved in 150 ml water containing 25 ml HCl with heating and stirring. The solution was then cooled down to 5 C. Of the sodium nitrate, 3.8 g (10 mmol) was dissolved in the minimum amount of water and then slowly added to the former solution. The reaction mixture was stirred for 1 hour in order to obtain a clear solution that shows the completion of diazotization. Ten grams of N-ethy-N-hydroxy ethylaniline dissolved in 80 ml water containing 9 ml HCl was added to the resulting mixture and the clear diazonium salt solution was then added gradually. The reaction mixture was stirred for 1 hour below 10 C. The solution pH was maintained at 7 by dropwise addition of sodium hydroxide solution (10%). In order to complete the reaction, stirring was continued for 3 hours. The synthesized dye was filtered, washed off with hot water, and dried. The structure of the synthesized disperse dye is shown in Figure 1.
