氟化银制备

1.将氯化银在110℃下干燥一昼夜，并粉碎至30目以下，然后将其薄铺在反应皿中，装入反应管中，在200℃下与氟气进行反应，当在排气中检测不出氯气时，再通氟气3h。整个过程需在干燥箱中进行，所得产品应在金属罐中保存。为防止AgCl，AgF2，AgF三组分混合物发生熔融，所以在反应初期应将反应温度控制在80℃以下，然后再慢慢地升高到200～250℃。

2.将相对密度为0.898的浓氨水缓慢地加入到2mol/L的硝酸银溶液中，搅拌成透明溶液，然后在搅拌条件下将甲醛水溶液加入上述溶液中，并将反应混合物放置1h后，滤出沉淀的银，用水洗涤，继而用乙醇、乙醚洗涤，在110℃下干燥。在室温下用上述方法制得的银粉与氟反应，便可得到黄褐色产物，但需注意反应温度不要高于60℃。反应结束时，逐渐将温度升高到250℃，即得二氟化银。用氟气作为反应物来合成二氟化银时，应注意尾气中氟气的处理。

3. 将50克新沉淀的氯化银在1IQ℃下干燥过夜，研细使能通过30筛孔的筛。然后将它撒布在反应盘中成一薄层。将反应盘装在反应器中，并在炉温为200℃下使其受氟的作用。使氟通过反应盘中的原料上面直到在放出的气体中检查不出氯的痕迹，然后再继续通氟3小时，用干燥氮气吹扫将氟排出。将一只有扣紧盖子的金属罐洗净烘干，用干燥氮气将罐中空气排除。然后将产物取出，在1一3秒内将产物移入金属罐中，随即将容器密闭.
