Physical and Chemical Properties | solubility: slightly soluble in hot chloroform, O-chlorophenol, pyridine (hot), insoluble in acetone, alcohol, toluene; Brown in concentrated sulfuric acid, blue precipitate after dilution; in alkaline powder solution in green blue, add acid to Red Blue. hue or shade: Red light blue |
Use | The pigment is a kind of anthraquinone vat dye, which gives red light blue color, excellent light resistance, weather fastness and good solvent resistance. Mainly used in industrial coatings, metal decorative paint, has excellent durability; Can also be used for plastic coloring. |
overview | reduced blue 6 is a blue powder, insoluble in water, slightly soluble in heat, chloroform, o-chlorophenol, hot pyridine. It is brown in concentrated sulfuric acid and turns blue after dilution. After the alkaline reduction solution is reduced to a leuco, it is green and blue, and the acid is added to become red and blue. |
chemical properties | blue-green powder. Insoluble in water, acetone, ethanol, toluene, slightly soluble in chloroform (heat), o-chlorophenol, pyridine (heat). It is brown in concentrated sulfuric acid and blue after dilution. It is green and blue in the alkaline solution of hydrosulfite, and red and blue in the acidic solution. |
use | reduced blue BC is used for dyeing cotton, viscose fiber, silk, vinylon and printing cotton cloth, with good levelness and affinity. It is also used for dyeing of sticky cotton and vitamin cotton blended fabrics, and also for preparing organic pigments. |
production method | 2-amino anthraquinone is used as raw material, sulfuric acid and manganese dioxide are added to dissolve after alkali melting, then chlorine is introduced to chlorinate, and the finished product is obtained through crystallization, pickling, reduction separation, filtration, crushing and drying.. |
