Haimeng study Industrial Co., Ltd. supply hydrosulfite antioxidants

Haimeng study Industrial Co., Ltd. of high-quality manufacturer, hydrosulfite sodium hydrosulfite manufacturers phone, sodium hydrosulfite sodium hydrosulfite CAS number, Shanghai hydrosulfite sodium hydrosulfite latest offer, sodium hydrosulfite detail even even dithionite and sodium hydrosulfite hydrosulfite Prices sodium sulfite, sodium hydrosulfite sodium hydrosulfite manufacturers latest offer, even the amount of sodium hydrosulfite sodium hydrosulfite, sodium hydrosulfite sodium hydrosulfite formula, molecular weight sodium hydrosulfite sodium hydrosulfite even. Dithionite, also known as sodium hydrosulfite, is a white or light yellow crystalline powder sand like chemicals, melting point 300 ℃ (decomposition), ignition temperature 250 ℃, insoluble in ethanol, soluble in sodium hydroxide solution, water a strong reaction and combustion. CAS No.: 7775-14-6; 7631-94-9 Molecular formula: Na2S2O4 Molecular Weight: 174.11 Physical properties: dithionite belong to a flammable when wet, also known as hypo. Commodities containing water of crystallization (Na2S2O4.2H2O) and non-crystalline water (Na2S2O4) two kinds. The former is white fine crystalline, which as a pale yellow powder. The relative density of 2.3-2.4, red hot decomposition, can be dissolved in cold water, hot water decomposition, soluble in ethanol. 7775-14-6 1. Appearance: White sand-like crystals or yellowish powder 2. Melting point (℃): 52 ~ 55 (exploded) 3. Boiling point (℃): 130 (decomposition) The relative density (water = 1) : 2.1 to 2.2 5. The ignition temperature (℃): 250 [5] 6. Solubility: soluble in water, soluble in ethanol. 7631-94-9 1. Appearance: white crystalline powder. 1. Relative density: 2.3 to 2.4 3. Solubility: easily soluble in water, soluble in alcohol. Uses: It is widely used to restore the textile dyeing industry, reducing cleaning, printing and bleaching and used as silk, wool, nylon and other fabric bleach, because it does not contain heavy metals, bleached after the fabric color is very bright, easy to fade. In various substances, it can also be used for food bleach, such as gelatin, sugar, candied fruit, and soap, animals (plants) oils, bamboo, clay of bleaching. It can also be used in organic synthesis, such as dyes, as a reducing agent in the production of drugs or bleach, sodium hydrosulfite is the most suitable wood pulp and paper bleaching agent. And it can be a lot of heavy metal ions such as Pb2 + in water treatment and pollution control, Bi3 + and so reduced to metal, can be used to preserve food and fruit. 7775-14-6 1. hypo more intense than reducing sulfite, reducing and bleaching of the strongest in sulfites bleach. China provides for candied fruit, glucose, sugar, sugar, caramel, candy, liquid glucose, dried fruit, dried vegetables, noodles, bamboo shoots, mushrooms and canned mushrooms, maximum use of 0.40g / kg. Residual amount of potato starch (as SO2 meter) ≤0.05gkg. Strong reducing agent capable of reducing a lot of salt to metallic. Analysis of nitrogen, ammonia and ammonium bicarbonate desulfurization solution. Polarographic development. Bleach. 2. widely used in dyeing industries, such as cotton fabric dyeing auxiliary and silky fabric bleach. Also used in medicine, mineral processing, copperplate printing. The paper industry as a bleaching agent. Food grade product is used as a bleaching agent, preservatives and antioxidants. 3. The light used in soaps, oily esters, pulp bleaching. The chemical industry for the manufacture Rongalite, sodium thiosulfate, thiourea, thiosulfate benzoic acid, six O VI (Medicine), synthetic dyes, but also for copperplate printing and analytical reagent. The printing and dyeing industry as a reducing agent, silk, wool bleaching agents, but also for the pharmaceutical industry, mineral, thiourea and synthetic sulfides and the like. 7631-94-9 widely used in printing and dyeing industry, such as cotton fabric dyeing auxiliary and silky fabric bleach. Also used in medicine and mineral processing, copperplate printing. The paper industry as a bleaching agent. Food grade product is used as a bleaching agent and preservatives, antioxidants.
