Properties and Applications:

red light yellow to orange. Yellow powder. Soluble in water, but soluble in ethanol, ethyl ether, benzene and ethylene glycol, slightly soluble in acetone. In purple sulfuric acid, and it will produce red after diluted precipitation. In a blue nitric acid, then turned into orange. Its water solution with hydrochloric acid was red, and the precipitation produce; Add sodium hydroxide solution unchanged, excessive yellow produced after precipitation. Copper ions in dyeing color green dark; Iron ions in a shallow color; Chrome ions in a slightly change. Discharge the gender is good. Mainly used for soap shading, in strong acid dye bath dyeing wool, also can dye leather. When used for paper to measure good color. Also can be used in the manufacture color amylum, paint, wood products, biological dyeing. Can also be used in medicine and cosmetics.
