Hazard Information

Description

CI 42735 is classed chemically as a triphenylmethane colour.

Chemical Properties

Blue powder. Easily soluble in water, the aqueous solution is purplish-blue. Addition of sodium hydroxide does not change the color, but a precipitate forms. Dissolved in ethanol, it is pure blue. In concentrated sulfuric acid, it is yellow to golden yellow, turning lemon yellow upon dilution. The color darkens slightly when dyed with copper or iron ions.

Preparation

4-(Diethylamino)benzaldehyde?(1 Moore) and 3-((Ethyl(m-tolyl)amino)methyl)benzenesulfonic acid?(2 Moore) condensation, garnish with heavy chromate salt-oxalic acid oxidation.

Flammability and Explosibility

Notclassified

Properties and Applications

bright blue. Blue powder, soluble in water, but soluble in ethanol for pure blue. The strong sulfuric acid dyes for yellow until golden brown, to dilute lemon yellow. The water solution is violet blue, encounter after sodium hydroxide are still violet blue, precipitation. Levelness and discharge performance is good. Dyeing copper and iron ion in the dark colored. Used for wool, silk and their blended fabric dyeing and printing directly, also used in leather and wood color, sometimes also used for leather shoes oil up graces role.
