Introduction of sodium metabisulfite

Sodium metabisulfite is white or yellow crystalline powder or small crystals, with a strong smell of SO2, specific gravity 1.4, soluble in water, acidic aqueous solution, with a strong acid contact with the release SO2 and generates the corresponding salts, long home air, the oxidation into Na2S2O6, so the product can go far. Higher than 150 degrees Celsius, ie the decomposition of SO2.

Sodium metabisulfite for the production of sodium hydrosulfite, sulfamethazine, caprolactam, etc., and chloroform, styrene sulfone and benzaldehyde purification. Photographic industry as a fixer ingredients. Perfume industry for the production of vanillin, for brewing industry preservatives, rubber coagulant and bleached cotton dechlorination agent. Organic intermediates, dyes, tanning as a reducing agent, for electroplating industry, oilfield wastewater treatment as well as for mine processing agents.
