Chrom, 8-[(5-Chlor-2-hydroxyphenyl)azo]-7-hydroxy-1,3-naphthalindisulfonsure Komplex Chemische Eigenschaften,Einsatz,Produktion Methoden
synthetische
5-Chloro-2-methoxybenzenamine diazo, and 7-Hydroxynaphthalene-1,3-disulfonic acid coupling, and then in water solution and formic acid chromium common heating, in 120 ~ 135 ℃ to keep four or more hours, make its formed chromium complex. In contain chromium acid alkali type dry for, in chrome complexation processes medium armor oxygen radicals for hydroxyl displacement.
Properties and Applications
dark purple. Deep purple powder. Soluble in water (purple) and ethanol, slightly soluble in soluble fiber element. In strong sulfuric acid are blue-ray red, it will be diluted red to a purple; In 10% of sodium hydroxide solution is red. Used for wool, silk and polyamide fiber dyeing and printing and direct discharge printing, also used in leather and electrochemical aluminum shading. Especially suitable for wool carpet and influential product of dyeing.
