| Hazard Information | Back Directory | [Chemical Properties]
Brown powder. Easily soluble in water; aqueous solution is greenish-yellow. Adding concentrated hydrochloric acid turns it to a maroon color with the formation of a precipitate. Adding concentrated sodium hydroxide turns it to a golden orange color with the formation of a precipitate. Slightly sensitive to hard water. Slightly soluble in ethanol. Red in concentrated sulfuric acid, turning to lavender upon 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. | [Flammability and Explosibility]
Notclassified | [Properties and Applications]
yellow. Brown powder. Soluble in water for green light yellow, slightly soluble in alcohol. The strong sulfuric acid dyes for red, diluted into shallow purple. The dye solution to join strong hydrochloric acid into Red sauce, accompanied by precipitation; Add thick sodium hydroxide solution to brown light orange, precipitation. Water-soluble, a little sensitive fights. In 90 ℃ the solubility of 60 g/L. For tender yellow light. In dye bath of copper ions in a little turned dark colored light and red (3 class); Iron ion in slightly turned dark colored light and red (category 4). For A class SDC classification. Used for cotton, viscose, silk, polyamide, polyester/cotton blended fabric dyeing and printing directly, can also be used for leather, paper and ink color.
