Sodium Nitrite CAS：7632-00-0
Sodium nitrite shares both naming and functional similarities with sodium nitrate, as both compounds are widely used as preservatives in processed meats like salami, hot dogs, and bacon. In industrial production, sodium nitrite is typically synthesized via the reduction of sodium nitrate, with the primary manufacturing process involving the absorption of nitrogen oxide gases into aqueous solutions of sodium carbonate or sodium hydroxide.
