| Abstract: | Using 2,4 - Diaminotoluene and 2 - Amino - 4 - sulfo - 4 - Bromo - 9,10 - anthraquinone as raw materials, C. I. acid blue 350 was synthesized by acylation, condensation, hydrolysis, sulfonylation. The key step of hydrolysis reaction was studied. The optimum reaction conditions of hydrolysis were obtained by experiments： Acidic conditions, alcohol consumption 1200 mL, time 19 to 21 hours, the yield of hydrolysis was 93 %. |
