Azo Dye Formation Mechanism. Web azo dyes are prepared in a two step reaction, the first being the synthesis of an aromatic diazonium ion from an aniline derivative. Web in the following, we have summarized some recent syntheses of azo dyes and the mechanism of azo dye / polymer conjugation.

Web phenol is dissolved in sodium hydroxide solution to give a solution of sodium phenoxide. The solution is cooled in ice, and cold benzenediazonium chloride solution is added. Web the azo dyes and pigments are manufactured on an industrial scale by the same reaction sequence in two stages, diazotization and azo coupling. Most azo dyes contain only one azo group but there are some that contain two or three azo groups, called diazo dyes and triazo dyes respectively. Web in the following, we have summarized some recent syntheses of azo dyes and the mechanism of azo dye / polymer conjugation. Finally, we indicate the principle of gewald's reaction and its. Web azo dyes are prepared in a two step reaction, the first being the synthesis of an aromatic diazonium ion from an aniline derivative. Web azo dyes are synthetic dyes and do not occur naturally. The next step is coupling of the diazonium salt with an aromatic compound (shown below. Overall, there are five strategies for the synthesis of azo.
