Uses and synthesis of Sodium sulfite powder
The conventional name for sodium sulfite is sodium sulfite. Sodium sulfite is an inorganic compound. Sodium sulfite powder is white particle powder at room temperature, has sulfur dioxide odor, is stable when dry, and is sensitive to humidity. Sodium sulfite soluble in water and glycerol, but insoluble in ethanol, Sodium sulfite can be used as a developer, in the preparation of cellulose sulfite ester, in the preparation of sodium thiosulfate, as a preservative for dried fruits and meat, as a deoxidizer in the printing and dyeing industry, and as a reducing chemical agent in chemical and laboratory production and synthesis.
Applications/Functions of Sodium sulfite powder
- Sodium sulfite powder can be used as a developer, for the preparation of cellulose sulfite ester, for the preparation of sodium thiosulfate, as a preservative for dried fruits and meat, as a deoxidizer in the printing and dyeing industry, and as a reducing chemical agent in chemical and laboratory production and synthesis.
- Sodium sulfite and reducing bleach have bleaching effect on food and strongly inhibit oxidase in plant food.
Physicochemical Property of Sodium sulfite powder
Sodium sulfite is a white crystalline powder, odorless and slightly sulphate tasting. Sodium sulfite is soluble in water and is alkaline in an aqueous solution. It has good stability, but may lose crystal water in humid and high temperature environment. It is reductive and can react with many oxides.
Production methodprocess of Sodium sulfite powder
Sodium sulfite can be prepared by passing sulfur dioxide into sodium hydroxide solution, and when sulfur dioxide is excessive, sodium bisulfite is formed. Alternatively, sulfur dioxide gas was injected into Sodium carbonate solution, and then sodium carbonate solution was added after saturation to obtain heptahydrate crystallization, and Sodium sulfite powder was obtained after heating and dehydration..
