FAQ

What are the physical and chemical properties of Germaniumtetrachloride (CAS: 10038-98-9)?

Germaniumtetrachloride (CAS: 10038-98-9) is a white crystalline solid with a molecular weight of 254.59 g/mol. It has a melting point of 67.5°C and a boiling point of 112.5°C. It is soluble in organic solvents like chloroform and benzene but is only slightly soluble in water. Chemically, it is highly reactive and prone to hydrolysis to form germanium dioxide and hydrogen chloride gas.

How is germaniumtetrachloride (CAS: 10038-98-9) typically synthesized?

Germaniumtetrachloride is typically synthesized by the reaction of germanium dioxide with chlorine gas: GeO2 + 2Cl2 → GeCl4. This process is conducted at elevated temperatures and is optimized for yield and selectivity using appropriate catalysts and reaction conditions.

What industries use germaniumtetrachloride (CAS: 10038-98-9)?

Germaniumtetrachloride (CAS: 10038-98-9) is widely used in the semiconductor industry for the preparation of high-purity germanium. It is also utilized in the pharmaceutical industry for the synthesis of certain organogermanium compounds, in the polymer industry for the modification of polymer properties, and in sensor technology for the fabrication of gas sensors.

What precautions should be taken when handling germaniumtetrachloride (CAS: 10038-98-9)?

Germaniumtetrachloride (CAS: 10038-98-9) should be handled with caution due to its high reactivity and toxicity. It should be stored in a well-ventilated area and handled under a fume hood. Personal protective equipment (PPE) such as gloves, goggles, and a lab coat is essential. In case of spills, the area should be flushed with water and the spill cleaned up carefully according to the Safety Data Sheet (SDS).
