| Hazard Information | Back Directory | [Chemical Properties]
When dissolved in water, the aqueous solution is jujube red. Adding concentrated hydrochloric acid does not change the color and remains jujube red. Adding concentrated sodium hydroxide solution turns wine red. When dissolved in ethanol, it turns magenta. When dissolved in concentrated sulfuric acid, it turns dark blue and ruby red after dilution. | [Preparation]
1,1-Bis(3-methoxy-4-aminophenyl)cyclohexane double nitriding, and 4,6-Dihydroxynaphthalene-2-sulfonic acid?(2 Moore) coupled. | [Properties and Applications]
Claret. Deep dark reddish brown powder, soluble in water, slightly soluble in ethanol for product red. The strong sulfuric acid dyes for blue, diluted into red. The water solution is purple caramel, add after strong hydrochloric acid color unchanged; Add thick sodium hydroxide solution to red wine. Levelness and white sex medium. Copper ions in dyeing color shade the dark, encounter iron ion colored light blue and dark micro. Suitable for wool, silk, polyamide fiber and its blended fabric dyeing and printing directly, can also be used for leather shading. General for dyed dark.
