Подготовка
4-Amino-3-hydroxy-7-nitronaphthalene-1-sulfonic acid diazo, and Naphthalen-2-ol matches that, in water solution and formic acid chromium common heating, in 115 ℃ keep 2 hours, and then mixed with batches of no complexation half the dye, and sodium hydroxide move into basic. The product is about 2 to 3 Moore single atoms chromium azo dyes. Then will the nitro reduction for amino, again with 4-Methylbenzene-1-sulfonyl chloride condensation.Свойства и приложения
