Description

Sodium sulfite is an inorganic compound with the chemical formula Na₂SO₃. It appears as a white, water-soluble solid and is commonly used as an antioxidant and preservative. This compound is also utilized in various industrial processes, including the softening of lignin in the pulping and refining processes of wood and lignocellulosic materials.

Application

  1. Industry Grade : Used in Dyeing and printing Industry ,as dechlorinating agent and bleaching agent, in leather and tanning industry as bleaching agent , developer agent , reductant agent , stabilizer agent , or used in papermaking, electronic and water treatment industry.

  2. Food Grade: In food industry as additive (E223) preservative, antioxidant and antimicrobic for fruits (dried, glazed and candled), vegetables (onions, potatoes, etc.), juices (citrus and grapes) and fish (shrimps and prawns). In silage treatment as antifermentative. In starch and sweeteners production as bacteriostatic.

  3. Photo Grade: In the photographic industry as component of developer bath .

  4. Pharmaceutical Grade : pharmaceutical industry for the production of chloroform, benzene and formaldehydephenylpropanoid Sulfone
