CAS 6300-37-4

Disperse Yellow 7

Description:

Disperse Yellow 7, with the CAS number 6300-37-4, is an organic compound primarily used as a dye in the textile industry, particularly for synthetic fibers such as polyester. It belongs to the class of disperse dyes, which are characterized by their ability to be dispersed in water and used for dyeing hydrophobic materials. This dye exhibits good lightfastness and washfastness, making it suitable for applications where durability is essential. Chemically, Disperse Yellow 7 is a yellow azo dye, which means it contains an azo group (-N=N-) that contributes to its color properties. It is typically applied in a dispersion form, allowing it to penetrate the fibers effectively during the dyeing process. While it is valued for its coloring properties, safety assessments indicate that, like many azo dyes, it should be handled with care due to potential health and environmental concerns. Proper safety measures should be taken during its use to minimize exposure and environmental impact.

Disperse yellow 7

CAS: 6300-37-4

Disperse Yellow 7 is a synthetic organic compound that belongs to the class of azobenzene. It is used as a dye in paints, plastics, and paper. Disperse Yellow 7 can be used for the treatment of wastewater from biological sources. Disperse Yellow 7 has been shown to be effective in reducing concentrations of nitrogen and phosphorus in effluent water from sewage treatment plants and other biological sources. The mechanism by which this occurs is not well understood, but it may involve the formation of hydroxyl groups on the molecule that are then able to react with dissolved oxygen (O2) in the water. This reaction produces higher energy molecules that are more likely to react with other substances found in wastewater, such as nitrate (NO3-), ammonia (NH3), or phosphate (PO4). The reactions that occur when Disperse Yellow 7 reacts with these substances produce lower energy molecules or ions that are less reactive than those found before treatment. This process is called "de-activation" and
