Patent Blue A is a pollutant due to its water solubility and difficult removal process. | | Preparation | 4-Formylbenzene-1,3-disulfonic acid and N-benzyl-N-ethylbenzenamine (2 Moore) condensation and oxidation. | | Flammability and Explosibility | Nonflammable | | Properties and Applications | colourful green light blue. Blue powder. Soluble in water, but soluble in ethanol is blue. The strong sulfuric acid are olive green, yellow precipitation after diluted. A transparent green light blue aqueous solution at room temperature without gathered tendency, add sodium hydroxide subject to change after cooling,heated to boiling color from blue to violet precipitate. In dyeing copper and iron ions become dark green color. For heavy chromate salt not sensitive. For wool, silk and polyamide fiber fabric dyeing and printing, and can also be used in leather, paper, cosmetics, soap, biological and rubber color.
