Indofix Blue MERI - Production method

Using 2-amino -4-sulfonic benzoic acid, 2-amino -4-sulfonic acid -6-nitrophenol, 2-sulfonic benzaldehyde, m (β-sulfate ethyl sulfone group)-N-ethylaniline and cyanuric chloride as raw materials, first 2-amino -4-sulfonic benzoic acid is diazotized and reduced, and condensed with 2-sulfonic benzaldehyde, then the 2-amino -4-sulfonic acid -6-nitrophenol is diazotized, coupled with the aforementioned condensation product, and then added copper sulfate complexation, and then reduced the nitro to a blue-based dye. Then the m (β-sulfate ethyl sulfone group)-N-ethylaniline and cyanuric chloride are condensed for the first time, and then the blue-based dye is condensed for the second time to obtain the product. The finished product is salted out, filtered and dried.
