Sodium nitrite

1. Sodium nitrite 2.Molecular formula; NaNO2 3.Product use ;Used as mordant, bleach, metal heat treatment, electroplating, corrosion inhibitor, also for making and potassium nitrate, azo dyes, etc 4.CAS number; 7632-00-0 5.Toxic protective Skin contact sodium nitrite solution limit concentration for 1.5%, greater than this concentration skin inflammation, appear when scaly. Accidental this product 3g can cause dizziness, nausea, in the loss of consciousness state. In central Asia sodium nitrate aerosol the maximum allowed by air concentration is 0.05 mg/L. Staff must wear uniform while operating, wear respirators, wear glove etc, in order to protect skin appliances for labor protection. Production equipment to be airtight, workshop to ventilation. 6.Packaging storage With the plastic woven bag lined with polythene film bag packaging, net weight of each bag is 50kg. Should be stored in a cool, dry and ventilated inside storeroom. Prevent heated, presenting contact kindling. Not with oxidant, organic matter, flammable and explosive substances, acids, sulfur yellow, food etc altogether storage mix of luck. Transportation to process to prevent rain and the strong sunlight. Notice moistureproof. This product shoulds not be long stored. Be careful when light put loading and unloading, prevent packing damage. Fire, water, sand and various fire extinguisher save. But avoid aqueous flow to inflammable goods place. 7. The physicochemical properties White or light yellow inclined FangJing department microstrip crystallization or powder. The relative density 2.168. Melting point °C 271. Micro salty. Easy ChaoXie. Soluble in water and liquid ammonia, the solution is alkaline (pH = 9). Slightly soluble in methanol, ethanol, without water. Dew on the air slow oxidized to sodium nitrate. Heated to 320 °C above decomposition liberate oxygen, nitrogen oxides, eventually generated oxidation sodium. With organic contact easy combustion and aeration Fried. Poisonous! 8.Quality standard GB/T 2367-2006;
