Properties and Applications
brown. Brown evenly powder. Soluble in water for orange brown, soluble in ethanol, slightly soluble in acetone and soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid in the dark for the light purple to violet black, diluted into a brown; In nitric acid partly dissolved for red light brown, to orange brown. The dye solution to join 10% sodium hydroxide solution for yellow brown. Cellulose fiber of dyeing, dye well after sex is good, temperature in 100 ℃, affinity is the largest. Discharge of more sensitive to that fights. Copper ions in dyeing and dark colored light yellow, meet iron ion to yellow. Mainly used for cotton, such as glue of cellulose fiber dyeing, also can be used for silk, polyamide fiber, Sticky/brocade fabric dyeing, can also be used for the pulp and leather color.
