二氧化锗制备

四氯化锗水解法在四氯化锗中加入6.5倍体积的蒸馏水，搅拌后放置一昼夜，生成二氧化锗沉淀，用冷水洗涤至洗液不含Ｃｌ－为止。于200℃干燥得到二氧化锗产品。其反应式：

图XＩＶ－１９　四氯化锗的蒸馏装置

在实验室里制备高纯的二氧化锗，是将市场出售的二氧化锗制成四氯化锗，再将其蒸馏提纯，水解得到的。

图四氯化锗的蒸馏装置制法［370］烧瓶内装入二氧化锗和浓盐酸，装置如图。玻璃管的前端要浸入水里一段，接受槽加少量冰水冷却。边通氯气边蒸馏，取110℃以前的馏分。在蒸馏中为了防止烧瓶中盐酸浓度下降，要时常从滴液漏斗滴加浓盐酸。向流到接受槽的四氯化锗层(黄色)和盐酸溶液层加大量水(H2O∶GeCl4＝65∶1)，摇匀，放置一昼夜。四氯化锗即水解为二氧化锗。过滤，用冷水洗涤，200℃下干燥。
