Verwenden
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.
Hazard
Toxic material
Sicherheitsprofil
Poison by intravenous
route. Mddly toxic by inhalation. A skin,
severe eye, and mucous membrane irritant.
Will react violently with water or steam to
produce toxic and corrosive fumes. When
heated to decomposition it emits toxic
fumes of Cl-. See also GERMANIUM
COMPOUNDS.
l?uterung methode
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.
