  • Description

    Chemical properties: yellow powder. Good water solubility, yellow to golden yellow solution in water, flocculent dye will precipitate if the solution is cooled. If 1g of dye is dissolved in 50mL of water, it will become frozen when it is cooled to ≤15 ℃, so it is called frozen yellow. The aqueous solution with concentrated hydrochloric acid had a reddish red precipitate; the concentrated alkali added to the Chemicalbook had a golden orange precipitate, and the diluted alkaline color changed slightly. Slightly soluble in ethanol (in lemon color), ethylene glycol ether and acetone (in green light yellow). It appears as red light purple in concentrated sulfuric acid. After dilution, it precipitates purple to red light blue precipitate. It does not dissolve in concentrated alkali and appears white after dilution. Yellow in concentrated ammonia.
