Uses and synthesis of Sodium bisulfite powder

Sodium bisulfite powder is also known as sodium bisulfite. Sodium bisulfite CAS 7631-90-5 is a colorless monochromatic crystal or white crystalline powder, with sulfur dioxide odor, molecular weight 190.10, relative density 1.48, decomposition at the melting point, unstable in the air, the release of SO2. Sodium bisulfite Raw Materials are soluble in water and the aqueous solution is acidic. The solution also has strong reducibility. In case of acid, it decomposes and releases sulfur dioxide.

Applications/Functions of Sodium bisulfite powder

• Sodium bisulfite powder can be used for bleaching cotton fabric and organic matter, and as a reducing agent in dyes, papermaking, tannery, chemical synthesis and other industries
• Sodium bisulfite CAS 7631-90-5 Sodium Bisulfite CAS 7631-90-5 is used in the pharmaceutical industry for the production of analamine and aminopyrine intermediates, and edible grade products are used as bleach, preservatives, and antioxidants.

Physicochemical Property of Sodium bisulfite powder

White monoclinic crystal. Smells of sulfur dioxide. Soluble in water, slightly soluble in alcohol.

Production methodprocess of Sodium bisulfite powder

Sodium bisulfite Raw Materials were prepared by absorbing sulfur dioxide from sulfuric acid tail gas with soda ash solution, centrifugation and air drying at 250-300 ℃.
