нитрит натрия

As send lubricious agent, Sodium nitrite is used in meat products processing.Sodium nitrite is used as a common analytical reagent, oxidant and diazotization reagent, also used for the synthesis of nitrite and nitroso compound .Used as a mordant, bleach, metal heat treatment, electroplating, corrosion inhibitor, medicine, used as instrument disinfectant and preservative, etc.Used as the production for ice dye, sulphur dyes, direct dyes, acid dyes, disperse dyes, basic dyes, hair dye, H hole aid. Also it is used in the production of amino azobenzene, para amino phenol intermediates, etc. Also it is used in production of organic pigments, such as silver bead R, bright red, big red, bright red candle, toluidine mauve, scarlet lake, lithol scarlet, fast bordeaux lake CK, etc. It is used in the manufacture of ethylamine pyrimidine, aminopyrin and so on in the pharmaceutical industry. It is used in the production of vanillin, and used as bleaching for silk and flax and mordant dyeing of fabrics. Also it is used for metal heat treatment and plating corrosion inhibitor. It is used for cutting oil, lubricating oil, antifreeze liquid and hydraulic system.Sodium nitrite is allowed to use the hair color agent in China. It is excluded nitrite under the action of lactic acid in the meat, and then decompose the nitroso (N0), the latter with myoglobin can generate nitroso myoglobin of the bright red color, and can produce a special flavor.
