Disperse Violet 26 Chemical Properties,Usage,Production

General Description

Disperse Violet 26 is a commercial dye, and the attachment of azo groups (N=N) a) is a very important feature of disperse dyes. Disperse Violet 26 is a fluorescent probe used as a commercially available fluorescent dye for the detection of ClO^- . ClO- is one of the important biologically active oxygen species (ROS)[1].

Flammability and Explosibility

Not classified

Synthesis

1,4-Diamino-2,3-diphenoxyanthraquinone is prepared from the 2,3-dichloro compound and phenol by chlorine replacement .

Properties and Applications

red light purple. brown-red powder, soluble in alcohol. The strong sulfuric acid in colorless, diluted red for yellow light. In dyeing calcium and magnesium ions not sensitive, encounter iron ion colored light slightly influence, copper ions in big effect. Dye bath appropriate pH value for 3 to 8, in dyeing and printing not alkali resistance. The dyes red light for purple, suitable for polyester/cotton blended fabric dyeing, and have a good color fastness to dry. Suitable for high temperature high pressure and hot melt dyeing method, hot melt temperature of 210 ~ 220 ℃. In three vinegar on fiber dyeing, colored light and polyester similar, is not suitable for dyeing two vinegar fiber, polyamide fiber and acrylic. But in polyester fabric weaving direct printing, cannot be printing the impression of the discharge. And Disperse Violet 26?and the same chemical structure.

Waste Disposal

Disperse dyes are recalcitrant in nature and nonbiodegradable, and therefore persistent dyes. At present, wastewater treatment containing dispersed dyes is very challenging, and oxidation is the most well-known and commonly used treatment method for destroying the dye structure. UV-H₂O₂-based systems are often used to improve dye degradation[2].
