Product Description Product DescriptionAnhydrous sodium sulfite, with the chemical formula of Na2SO3 and a molecular weight of 126.04, is commonly known as sulfur oxide powder or sulfur powder and is an important chemical. It is a white powder or hexagonal prism crystal with a strong smell of sulfur dioxide. It is easily soluble in water, and the aqueous solution is alkaline with a pH value of about 9~9.5. It is slightly soluble in alcohol and insoluble in liquid ammonia.Physical propertiesThe solubility of anhydrous sodium sulfite in water varies greatly with temperature. The solubility is 12.54g/100ml water at 0oC, 28.3g/100ml water at 80oC, and the highest solubility is about 28g/100ml water at 33.4oC. It is easily oxidized under the action of humid air and sunlight, but is more stable than sodium sulfite heptahydrate; it will decompose to form sodium sulfide and sodium sulfate when heated.Chemical propertiesAnhydrous sodium sulfite has strong reducing properties, reacts with sulfur dioxide to form sodium bisulfite, reacts with strong acid to form corresponding salt and releases sulfur dioxide. It is easily oxidized under the action of humid air and sunlight to produce sodium sulfate. It will decompose into sodium sulfide and sodium sulfate when heated.Application fieldsAnhydrous sodium sulfite has a wide range of applications in many fields:Water treatment: used as a deoxidizer for boiler water and oil field injection water, and a dechlorinator for municipal water or industrial waterPrinting and dyeing industry: as a deoxidizer and bleaching agent to prevent cotton fibers from being damaged by local oxidation and improve the color and quality of printing and dyeing productsChemical industry: used as a raw material for the production of chemical products such as sodium thiosulfate, hydrosulfite, sodium pyrosulfite, and is also a catalyst and reducing agent for certain chemical reactionsPapermaking industry: used as a remover of wood cellulose to improve pulp quality and paper strengthFood industry: used as a bleaching agent, preservative, loosening agent and antioxidant to extend the shelf life of food Product Parameters SSA(PH 8-10)ITEMSSTANDARDSODIUM SULPHATE99.0%MINWATER INSOUBLE MATTER0.05%MAXCHLORIDE(AS CL)0.35%MAXCa+Mg(as Mg)0.15%MAXIRON(FE)0.002%MAXMOISTURE0.2%MAXWHITENESS82MINPH8-10 SSA(PH 6-8)ITEMSSTANDARDSODIUM SULPHATE99.0%MINWATER INSOUBLE MATTER0.05%MAXCHLORIDE(AS CL)0.35%MAXCa+Mg(as Mg)0.15%MAXIRON(Fe)0.002%MAXPH6-8WHITENESS82MINDENSITY1.45g/ml MAX Detailed Photos Packaging & Shipping Company Profile Hubei Highwin New Material Technology Co., Ltd. focuses on the research and development, production and sales of epoxy resin and other chemical raw materials.
