Description

Minimum delivery from one bag, 25kg

Sodium nitrite - is a salt of nitrous acid - a colorless or slightly yellowish crystals, readily soluble in water, hygroscopic. Melting point 284 ° C; decomposition temperature> 320 ° C; density 2. 17 g / cm³; solubility in water 82 g / 100 ml (20 ° C). An aqueous sodium nitrite solution is alkaline.


Sodium nitrite is a fire hazard substance, promotes self - ignition of combustible materials, is obscheyadovitym toxic substance. In the air slowly dookislyaetsya to sodium nitrate NaNO 3 . He is a strong reducing agent.

Chemical formula: NaNO2

Sodium nitrite is widely used in various industries. In the building industry technical sodium nitrite in the form of a powder according to GOST 19906 - 74 or an aqueous solution is recommended as an additive to concrete ensures resistance to frost, as a means to protect against corrosion of constructions.
In the chemical industry, sodium nitrite is used in the production of diazo dyes, nitro compounds and other organic compounds, as an oxidant in the processes of isolation Yoido iodine, in the chemical synthesis for the formation of a diazo amine compounds.
In the food industry (food additive E250) is involved in the processes of the production of sausages as an antioxidant (to give a smoked and sausages characteristic pink - red color) and a preservative (antimicrobial agent), in medicine as a bronchodilator and a vasodilator, and as an antidote to cyanide poisoning.
