Manufacturing Methods : 5-Chloro-2-methoxybenzenamine diazotization, and 6-Hydroxynaphthalene-2-sulfonic acid coupling, and then in water solution and Chromium formate heating, in 125 ~ 135 ℃ keep 7 hours, make its formation Chromium complex, in chrome complex process medium armor oxygen base displacement into hydroxyl (C.I. acid Violet 56, C.I. 16055). (a) Phthalic anhydride and 3-(Diethylamino)phenol condensation, alkali fusion, with sulfuric acid acid solution, and using hydrochloric acid crystallization, (b)2-(3,6-Dichloro-9H-xanthen-9-yl)benzoic acid and Diethylamine in pressure reaction (BP960088) (C.I. Basic violet 10, C.I. 45170). Then two dye generation complex.
Properties and Applications:brilliant red. Soluble in water is purple, soluble in ethanol, slightly soluble in Cellosole. In concentrated sulfuric acid to blue light red, red after diluted to purple; In 10% of sodium hydroxide solution for blue purple. Dye aqueous solution to join 10% sulfuric acid solution blue. Used for alcohol, esters solvent, alcohol soluble and synthetic resin paint, printing ink, wood color.
