Also used as food bleaching agent, preservative, color fixative, osteoporosis agents, antioxidants and preservatives, dyeing mordant food grade sodium metabisulfite, sodium metabisulfite rubber coagulant price, but also the production of chloroform, benzene and formaldehyde solasulfone raw materials. 3 food industry as a bleaching agent, preservative, osteoporosis agents, anti-oxidants, color agents and preservatives. 4 reagents for the analysis. Also used as a reducing agent, preservatives, antioxidants. Used in the synthesis of dyes, pharmaceuticals industry. The nature and stability of sodium metabisulfite 1. Damp easily decomposed, exposed in air easily oxidized into sulfate. Irritation. 2 Contact with acid emit sulfur dioxide and generate the corresponding salts. Heated to 150 ℃ decomposition. SO2 white powder with a strong odor, and lost in the air absorbing SO2 and O2 into Na2SO4. Soluble in water, acidic aqueous solution, when the solution is heated to above 65 ℃, ie decomposition of Na2SO3 and SO2. Sodium metabisulfite uses sodium metabisulfite, Rui Desheng Chemical provided by 瑞德胜 chemical. If you have any questions about this information or consultation, please contact us now!
