SIRIUS YELLOW GC Chemical Properties,Usage,Production

Chemical Properties

Brown powder. Easily soluble in water, the aqueous solution is greenish yellow, adding concentrated hydrochloric acid turns to sauce red, accompanied by precipitation; adding concentrated sodium hydroxide turns to golden orange, accompanied by precipitation, slightly sensitive to hard water. Slightly soluble in ethanol. Red in concentrated sulfuric acid, lilac after dilution.

Uses

Direct yellow 44 (CAS# 8005-52-5) is a water-soluble organic azo dye and water pollutant.

Preparation

3-Aminobenzenesulfonic acid diazo, and (2-Methoxyphenylamino)methanesulfonic acid coupling. Then the water with sulfonic acid base, compounds (A) (coupling components is O-Anisidine with Formaldehyde?and sodium sulfite and processing); 4-Nitrobenzenamine diazo, coupled with 2-Hydroxybenzoic acid, and then will the nitro reduction, compound (B). Finally the molecular A and B mixture light gasification.
