Chemische Eigenschaften
Colorless liquid. decomposes in water. Insoluble in concentrated hydrochloric acid; soluble in carbon disulfide, chloroform, benzene, alcohol, and ether.
Physikalische Eigenschaften
Colorless liquid; density 1.879 g/cm³ at 20°C and 1.844 g/cm³ at 30°C; refractive index 1.464; boils at 86.5°C; solidifies at -49.5°C; decomposes in water; soluble in alcohol, ether, benzene, chloroform and carbon tetrachloride; insoluble in concentrated hydrochloric and sulfuric acids.
Verwenden
It is used as a catalyst in the conversion of carbohydrates into 5-hydroxymethylfurfural in ionic liquids, as a reducing agent in combination with triphenylphosphine (TPP) for the reduction of alpha-bromo carboxylic acid derivatives, and in the production of pure germanium. It also finds use as an intermediate for several optical processes. It is one of the most important dopants in silica glass for optical fibers. It is employed in the preparation of germanium dioxide which is used for wide camera lens, microscopy, IR-transparent glasses/windows/lenses, and for the core of fiber-optic lines.
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
Flammability and Explosibility
Non flammable
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.
läuterung 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.
