C.I.Reactive Blue 20 - Introduction
Reactive Blue 20 is a synthetic organic dye with the chemical name Reactive Blue 20, also commonly known as Remazol Brilliant Blue R. It has bright blue color, good light fastness and washability, and is widely used in fiber dyeing.
Reactive Blue 20 is a kind of Reactive dye, its molecule contains Reactive groups, can form covalent bonds with cellulose, protein and polyamide and other fiber materials. This enables the dye to be firmly bonded to the surface of the fiber, is not easy to fall off, and has good durability and color fastness.
Reactive Blue 20 dye is mainly used for textile and leather dyeing. It can be gently combined with fibers, making the dyeing process more efficient, controllable, and uniform and bright colors. In addition, it can also be used in the printing industry, especially in silk printing, with good printing results.
The preparation of Reactive Blue 20 is mainly through multi-step synthesis. First, an aniline compound is reacted with an aromatic aldehyde to produce a dihydric aromatic amine. Then, the diamine is reacted with the phenolic compound to produce an azo compound. Finally, the azo compound reacts with an aromatic amine to produce Reactive Blue 20.
Regarding safety information, Reactive Blue 20 is an organic dye, and the following should be noted when using it:
1. Avoid contact with eyes, skin and clothing, avoid inhalation or ingestion.
2. Wear protective gloves and appropriate protective clothing during use.
3. In case of accidental contact, rinse the contaminated area immediately with plenty of water.
4. Dye storage should avoid contact with flammable and easily oxidized substances, and keep the container closed.
Overall, Reactive Blue 20 is a commonly used dye with good dyeing properties and durability. In the use of the process should be careful to operate, comply with the relevant safety regulations, to ensure personal safety and environmental safety.
