azosulfonfärgämnen
Azo sulfon dyes are a class of synthetic organic dyes characterized by the presence of both an azo group (-N=N-) and one or more sulfonate groups (-SO3-) in their molecular structure. The azo group is the chromophore responsible for the color, while the sulfonate groups typically confer water solubility. These dyes are widely used in various industries due to their vibrant colors, good tinctorial strength, and relatively low cost of production.
The synthesis of azo sulfon dyes generally involves a two-step process: diazotization and coupling. In the first
Azo sulfon dyes find applications in textile dyeing, particularly for natural fibers like cotton, wool, and
