Usage

Description

Acid Red 226 is a synthetic azo dye characterized by its red color. It is available as a red powder and is slightly soluble in water. It is also soluble in various organic solvents such as ethylene glycol ether, DMF, and ethanol, resulting in a deep red solution.

Uses

Used in Leather Industry:
Acid Red 226 is used as a dye for pigskin, including cow leather and goat natural leather. It is particularly suitable for aniline leather spraying and shading. It is also used in the finishing of leather products, such as sprays or curtains.
Standard:
Acid Red 226 meets the following standards in terms of light fastness, soaping, perspiration fastness, oxygen bleaching, and fastness to seawater:
Light Fastness: ISO 6
Soaping: 5
Perspiration Fastness: 4-5
Oxygen Bleaching: 5
Fastness to Seawater: 2-3
These standards indicate the dye's performance and resistance to various conditions, making it a reliable choice for the leather industry.

Preparation

2-Amino-4-nitrophenol and 2-Amino-5-nitrophenol?diazo respectively, and 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one (2 Moore) coupling, and then make the generation of the chrome complex.
