Product Name: Food Grade Sodium Metabisulfite/sodium pyrosulfite SO2 65%
Application: Used as a food preservative. It is a slight hazy solution free from inappropriate impurities. These sulphites are available in white and faint cream crystalline free flowing powder and are widely used in photographic chemical and preservative chemical.Used in medicine when producing chloroform,solasulfone and methnylal;used as coagulant in rubber industry; used as dechlorided agent or assistants in printing and dyeing industry; used to improve leather properties in leather industry; used as developing agent in photosensitivity industry; used when producing hydroxyl geranial, hydrochloric hydroxylamine in chemical industry; used as bleaching agent, antiseptics, antioxidant, ect.in food industry.
Sodium metabisulphite white or yellow crystalline powder or small crystallization, with strong smell, a proportion of SO2 1.4, soluble in water, become acidic aqueous solution, and acid contact is released SO2 generated corresponding salts, long for air, is oxidized to Na2S2O6, reason this product not far. Above 1500C, namely the SO2 decomposition.
