trisodium 5-acetamido-4-hydroxy-3-[2-hydroxy-5-(2-sulfonatooxyethylsulfonyl)phenyl]azo-naphthalene-2,7-disulfonate - Production method
Using p-(2-sulfate ethyl sulfone group) aniline and acetyl H acid as raw materials, the p-(2-sulfate ethyl sulfone group) aniline is first diazotized, then coupled with acetyl H acid, and then oxidized and complexed to obtain the product. The finished product is salted out, filtered and dried..
Add 300L of water and 145kg of p (2-sulfate ethyl sulfone group) aniline into a diazo pot, stir, add 45kg of soda ash, control the pH value to 7.5, and dissolve all the materials. Add 130kg of hydrochloric acid, cool to 0-2 ℃, add 30% sodium nitrite solution, maintain 5-8 ℃, add stirring for 30min, neutralize with soda ash to pH 4.
Add N-acetyl H acid solution (obtained by acetylation of 170.5kg H acid) into the coupling pot, cool to 5 ℃, add the above diazo solution, stir for 1h after adding, neutralize with 20% soda ash to a pH value of 6-6.7.
Add 1kg of 12% copper sulfate disodium hydrogen phosphate solution into the coupling pot and stir for 30min. 550kg of hydrogen peroxide was added at 25-30 ℃ for 3h, and stirred for 4h to the end point. Then add potassium chloride to salt out, stir for 8 hours, filter and dry to obtain the finished product.
