Anthraquinone-2-Sulfonic Acid Sodium Salt (CAS 131-08-8) is a technical purity, water-soluble anthraquinone derivative. It is used as a catalyst in the kraft pulping process and as an intermediate in anthraquinone dye synthesis.
Product Specifications and Applications
Anthraquinone-2-sulfonic acid sodium salt (CAS 131-08-8) is a water-soluble anthraquinone derivative. Its water-soluble form offers a handling advantage over parent anthraquinone in aqueous pulping systems.
Key Applications:
- Kraft Pulping Catalyst: Utilized in cellulose and paper manufacturing. At 0.05-0.1% addition to the kraft cook, it accelerates delignification, improves pulp yield, reduces kappa number, and enables a lower alkali charge.
- Anthraquinone Dye and Vat Dye Intermediate: Serves as an intermediate in anthraquinone dye synthesis for textile applications.
- Electrochemical Research: Functions as a redox mediator.
- Analytical Chemistry: Employed as a redox indicator.
