Sodium Nitrite Salt For Dyeing And Bleaching Of Fiber Textiles 99% NaNO2
Sodium nitrite (NaNO₂) is an inorganic salt formed by the combination of nitrite ions and sodium ions. Pure sodium nitrite is a white to light yellow crystal. Sodium nitrite is deliquescent, easily soluble in water and liquid ammonia, and its aqueous solution is alkaline, slightly soluble in organic solvents such as ethanol, methanol, and ether. Sodium nitrite has a salty taste and is sometimes used to make fake table salt. In the air, sodium nitrite will be slowly oxidized to sodium nitrate (NaNO3). Sodium nitrite is easy to explode in contact with organic matter.

Sodium nitrite is often used as a metal heat treatment agent, and a 10% aqueous solution is also used for electroplating. It is a corrosion inhibitor for electroplating, a corrosion inhibitor for steel, and a bleaching agent for silk and flax. Sodium nitrite is also used as a mordant for fabric dyeing. The dye industry is used in the manufacture of dye intermediates, as well as ice dyes, sulfur dyes, direct dyes, disperse dyes, acid dyes, basic dyes and other dyes. In the pigment industry, it is used in the manufacture of pigments such as silver vermilion, scarlet powder, candle red, toluidine purple, and Lithol scarlet. Chemical analysis reagents, medical vasodilators, and raw materials for the manufacture of potassium nitrite, nitro compounds, azo dyes, etc., and are also used in medicine to sterilize instruments. It is used as a coloring agent, antimicrobial agent and preservative in the processing of meat products.
