Reactive Red 261 - Introduction
A Reactive Red 261 (also known as a Reactive Red 261) is a chemical dye that belongs to the class of Reactive dyes.
Nature:
Reactive Red 261 is a strong cationic dye with a bright Red color. It is soluble in water and has good colorability and light stability. In addition, it also has excellent temperature and alkali resistance.
Use:
Reactive Red 261 is widely used in the textile, leather and pulp industries. It can be used as a dyeing agent to dye textiles, leather and pulp. It can react with the hydroxyl and amino groups in the fiber to form a covalent bond with the fiber, so it can produce a strong dyeing effect and has good durability.
Method:
Reactive Red 261 is prepared by reacting a suitable aromatic amine compound with a Reactive agent containing a Reactive group (e. G., Halide, sulfonate, etc.). This reaction is usually carried out under basic conditions and heated to facilitate the reaction. Finally, the product is purified and treated by adsorption, washing and drying.
Safety Information:
The Reactive Red 261 is relatively safe under normal use. However, like other dyes, it still needs to be handled with caution. Avoid inhaling its dust or solution during use. In case of contact with skin or eyes, rinse immediately with plenty of water. If ingestion or inhalation occurs, seek medical attention. In addition, Reactive Red 261 should be stored in a dry, cool place, away from fire and combustibles.
