Sell Sodium Nitrite

Description

English name: Sodium Nitrite CAS No.: ********0 Molecular formula: NaNO2 Molecular Weight: *9.*1 pH: Melting point (℃): **1 Boiling point (℃): **0 (decomposition) Relative density (water = 1): 2.*7 Solubility: soluble in water, slightly soluble in ethanol, methanol, ether. Properties and applications: are amines, is white or light yellow rhombic crystals, soluble in water and liquid ammonia, slightly soluble in methanol, ethanol, ethyl ether, hygroscopicity strong, for fabric dyeing mordant; silk, linen The bleaching agent, metal heat treatment agent; steel corrosion inhibitor; cyanide poisoning *****, laboratory analysis reagents used in meat products, hair color processing agents, anti-microbial agents, preservatives. Density 2.**8g/cm3, melting point **1 ℃, decomposition at **0 ℃. Moisture absorption, soluble in water, aqueous stability and performance of alkaline reaction, can absorb oxygen from the air, and the formation of sodium nitrate. Toxic sodium nitrite, sodium nitrite is rumored to carcinogenic substances, but in fact is not a carcinogen sodium nitrite, sodium nitrite is carcinogenic under certain conditions, generate nitrosamines, nitrite molecules in , the nitrogen valence is *3. Compounds is an intermediate state, there are both reducing oxidation, such as KI in acidic solution can oxidize iodine: This reaction can be quantitatively carried out for determination of nitrite. Sodium nitrite used in the dye industry and a large number of organic synthesis, commonly used in the preparation of azo dyes, nitrogen oxides, drugs, anti-rust agent and dyeing, bleaching, bacon, etc., because it is toxic, use should be noted. High thermal stability of sodium nitrite, can be prepared by thermal reduction Packing Method: Two-layer plastic bag or outside the bag, plastic bags, latex bag; outside the compound plastic woven bags (polypropylene bags triple, triple polyethylene bags, polypropylene Combo bags, polyethylene Combo kits); thread mouth bottle, manhole covers for scrap pressure mouth glass bottles, plastic bottles or metal drums (can) outside the ordinary wooden box; thread mouth bottle, plastic bottle or tin-plated steel sheet barrel (tank) full floor outside latticed boxes, fibreboard boxes or plywoodboxes.
