Description
Silver oxide, chemical formula Ag2O. Molecular weight 231.74. Brown black cubic crystal or powder. The light gradually dissolves into silver and oxygen. Specific gravity 7.143(16.6℃). At 60 ~ 80℃ dry nearly black, hot to 300℃ decomposition, 250 ~ 300℃ decomposition accelerated. Slightly soluble in water and alkaline reaction, soluble in ammonia, potassium cyanide solution, nitric acid, sodium thiosulfate solution, difficult to dissolve in ethanol. Moisture can absorb carbon dioxide from the air. In the presence of alkali, formaldehyde aqueous solution can reduce it to metallic silver. Friction with combustible organic matter will cause combustion. After its ammonia solution for a long time, sometimes precipitated with strong explosive black crystals, may be silver nitride Ag3N or silver imimide Ag2NH. In organic synthesis, hydroxyl groups are often used to replace halogen atoms, or as oxidants, or as colorants in the glass industry. It is prepared by the action of silver nitrate solution with sodium hydroxide solution. Application 1. Electrode materials for silver oxide batteries 2. It is used to convert organobromine and chloride into alcohols, to convert phenyl methyl halide into phenyl methyl ether, and to be used together with iodine methane as methylation reagent. 3, For surface catalyst 4, Used to prepare water purifier Packing specification Finished product packaging: 50kg/barrel or as request Sample package: 500g/bottle or 1kg/bottle Specification:
