Products Description of Sodium nitrite CAS#7632-00-0

Sodium nitrite is similar in name and use to sodium nitrate. Both are preservatives used in processed meats, such as salami, hot dogs, and bacon. Sodium nitrite has been synthesized by several chemical reactions that involve the reduction of sodium nitrate. Industrial production of sodium nitrite is primarily by the absorption of nitrogen oxides into aqueous sodium carbonate or sodium hydroxide.
