亚硝酸钾 (CAS No.7758-09-0)
- 中文别名
- Nitrous acid, potassium salt Molecular Formula:KNO2 Physical Properties:Molecular weight: 85.11. White or pale yellow prismatic crystals, deliquescent. Easily soluble in liquid ammonia and water, aqueous solution is alkaline. Slightly soluble in alcohols, insoluble in acetone. Decomposes at 350°C to form potassium oxide and release nitrogen oxide gases. It is an oxidizer, toxic. Contact with organic materials and combustibles can cause combustion and explosion, releasing toxic and irritating nitrogen oxide gases. Mixing with iron salts or cyanides may explode. Hazard classification: GB 5.1 class 5107.
