Reactive yellow 167 - Introduction
Reactive yellow 167 (Reactive yellow 167) is a Reactive dye, also known as disubstituted sulfone acid dye. The following is a description of its nature, use, preparation and safety information:
Nature:
-Reactive yellow 167 is a crystalline powder with a yellow color.
-It has good solubility and ionic properties, and can be covalently bonded with fiber raw materials.
-It has good light resistance and washing resistance, and can be used for dyeing textiles and leather articles.
Use:
-Reactive yellow 167 is mainly used in textile dyeing and printing, especially for cotton, linen, silk and wool fibers.
-Due to its good dyeing properties, the dye can also be used in leather processing.
Method:
-The preparation of reactive yellow 167 usually starts from a disubstituted sulfuric acid structure.
-First, a nitroso compound is reacted with a disubstituted sulfone acid to generate a disubstituted sulfuric acid.
-Then, the disubstituted sulfuric acid is converted into the corresponding amine through a reduction reaction.
-Finally, through a coupling reaction with an azo compound, a reactive yellow 167 dye is generated.
Safety Information:
-Reactive yellow 167 are industrial dyes that can cause eye and skin irritation.
-During use, care must be taken to avoid contact with skin and eyes, and avoid inhaling its dust.
-Wear appropriate protective gloves, glasses and masks when using.
-Avoid contact with strong oxidants and combustibles during storage and handling.
-In case of discomfort or accidental contact, wash immediately with plenty of water and seek medical help.
