Textile Dyeing Case: A textile factory wants to produce a batch of red - dyed cotton fabrics. They use disodium 2-naphthol-3,6-disulfonate as an intermediate in the dye synthesis process. First, they mix a certain amount of this compound with other reactants in a reactor according to a pre - designed formula. The reaction is carried out under specific temperature and pH conditions. After the reaction is completed, the synthesized dye is purified and then used for dyeing the cotton fabrics. The result is a batch of red - dyed cotton fabrics with excellent color - fastness and vividness, which meets the market requirements.
Analytical Chemistry Case: A laboratory needs to determine the concentration of lead ions in a water sample. They use disodium 2-naphthol-3,6-disulfonate as a reagent. A small amount of the product is added to the water sample, and a complex is formed with lead ions. The absorbance of the complex is measured by a spectrophotometer. By comparing with a standard curve, the concentration of lead ions in the water sample can be accurately determined.
