Sodium sulfite 7757-83-7 for food preservation textile bleaching water dechlorination

Sodium sulfite, CAS 7757-83-7, is a common inorganic sulfite salt with stable reduction performance and excellent water solubility. The compound features mild chemical activity and non corrosive characteristics, suitable for long term industrial application. It is widely adopted in water treatment, textile processing, paper making and fine chemical industries as a professional deoxidizer, dechlorinating agent and antioxidant.

Sodium sulfite is a white crystalline inorganic salt with stable physical properties at room temperature. It dissolves quickly in water to form a clear solution with weak alkalinity. The product has mild and controllable reducibility, capable of removing residual chlorine and dissolved oxygen in water. It is non toxic and low corrosive, with stable reaction performance during industrial use. It will be gradually oxidized to sodium sulfate when exposed to air, and reacts with acid to release sulfur dioxide gas.

In water treatment, it serves as oxygen scavenger and dechlorinating agent to purify industrial circulating water and boiler water. In textile and paper industry, it acts as gentle bleaching agent to protect fiber and paper texture. It also works as antioxidant and preservative in chemical synthesis, food processing and pharmaceutical production, effectively preventing raw material oxidation and deterioration.

Continuous and stable reduction effect avoids excessive reaction damage. Fast water dissolution improves industrial operating efficiency. Low impurity content ensures clean reaction results. Mild property reduces equipment corrosion and application risks, meeting standard industrial production requirements.
