The key to this product is the preparation of 2-methoxy-5-benzanilide. Reaction equation Operating process: 37.8 parts of 2-methoxy-5-formic acid nitrobenzene, 216 parts of benzene and 18 parts of aniline, heated to 75℃, added dropwise alkali trichloride, acylated at 107～110℃ for 8h, filtered and dried . 33 parts of the dried substance and 40 parts of zinc powder were added to 245 parts of glacial acetic acid to carry out a reduction reaction for 8 hours to obtain 2-methoxy-5-benzoanilide with a yield of 93%. Add 47.6kg of red base KD to the diazonium pot, add water and hydrochloric acid at 20°C and stir, cool the color base solution to 0°C, diazotize with 34.2kg 40% sodium nitrite solution, filter, and use the diazonium solution for later use. Weigh 59.8kg of Naphthol AS into 500L of dissolved sodium in water, add 52.6kg of 33% caustic yellow, heat to 92℃, add to a coupling pot with water and ice, and precipitate with hydrochloric acid. Suspension Congo Red The test paper turns blue. The diazonium solution was added to the chromol suspension at 15°C, and 161.5kg of sodium acetate crystals were added at the same time, stirred for 1 hour, filtered, washed with water to neutrality, and dried to obtain the finished product.
