描述

产品介绍 300°C时会完全分解。氧化银是立体的共价聚合物,难溶于大多数溶剂中。它在水中可略微溶解,生成Ag(OH)2–离子及类似的水解产物,水中溶解度 0.0013 g/100 ml (20°C) 。溶于生成可溶性银盐的酸中,也可与氨水、碳酸铵、氰化钾和氰化钾溶液配合而溶解。
别名 氧化银 ;silver(II) oxide
应用 氧化银是氧化银电池的电极材料。它也是有机合成中的弱氧化剂和弱碱,可与1,3-二取代的咪唑盐及苯并咪唑盐反应生成氮杂环卡宾,可替代不稳定的配体环辛二烯或乙腈作卡宾转移试剂,合成过渡金属卡宾配合物。此外,氧化银可在低温和水汽存在下将有机溴化物和氯化物转化为醇类,把苯甲基卤化物转化成苯甲基醚,与碘甲烷连用为甲基化试剂,用于糖类甲基化分析和霍夫曼消去反应中,以及将醛氧化为羧酸。也作为表面催化剂,用于烯的环氧化反应中。
