解説GeCl4(214.45).二酸化ゲルマニウムを塩酸に溶解するか,ゲルマニウムを塩素気流中で加熱すると得られる.ゲルマニウムの塩化物中もっとも安定で,常温で無色の液体.融点-49.5 ℃,沸点84.0 ℃.密度1.84 g cm-3.水と徐々に反応して酸化ゲルマニウム(Ⅳ)と塩酸になる.GeCl4は有機化合物と付加物をつくりやすく有機溶媒によく溶ける.GeCl4の揮発性はゲルマニウムの精製に利用される.
使用Germanium(IV) chloride is used in the microwave preparation of Ge2Cl6, a colorless crystalline material which was included in a further study of low-valent germanium compounds.1 Germanium(IV) chloride is used in the preparation of many germanium compounds.
純化方法Traces of Cl2 and HCl can be removed from the liquid by blowing dry air through it for a few hours at room temperature or by shaking it with Hg or Hg2Cl2 and then fractionating it in a vacuum. It decomposes on heating at 950o. It has a sharp penetrating odour and fumes in moist air to give a chalky coat of GeO2. It is slowly hydrolysed by H2O to give GeO2, but distils from conc HCl.

Glass powder (100-300 mesh). Washed with 10% HNO3, water and dry in air.
