Molecular FormulaC37H28N6Na4O17S4
Molar Mass1048.8673
Density1.606[at 20℃]
Water Solubility2.14g/L at 20℃
Vapor Presure0Pa at 25℃
Storage ConditionRoom Temprature
Physical and Chemical PropertiesSoluble in water, the aqueous solution is red to blue red, in water solubility of 15g/L (60 ° C), 24g/L (97 ° C), very sensitive to hard water. The addition of concentrated hydrochloric acid to the aqueous solution resulted in a blue-green precipitate; The addition of concentrated sodium hydroxide solution resulted in a yellow-orange color. Slightly soluble in ethylene glycol ether, insoluble in other organic solvents. Blue in concentrated sulfuric acid, diluted purple; Blue-black solution in concentrated nitric acid, then turned blue, and finally olive. Slight color change of copper and iron ions during staining.

use direct sun-resistant red 4BL is used for dyeing cotton and viscose fabric, with good dyeing rate and slightly poor dyeing and levelness. It is also used for direct printing of cotton and viscose fabrics, white printing of ground color and white printing, as well as printing on silk and wool fabrics. It can also be used with disperse dyes to dye polyester-viscose blended fabrics in the same bath and for coloring leather, paper and aluminum oxide.
Production method Using H acid, Clitidine and phosgene as raw materials, the H acid is first diazotized, then coupled with Clitidine, and then the two-molecule coupling product is condensed with a molecule of phosgene to obtain the product. The finished product is salted out, filtered, dried and crushed..
