Recovery of Germanium tetrachloride_ Germanium chloride recovery_ Rare metal recycling manufacturers

Germanium tetrachloride (GeCl4) is a Inorganic compound consisting of one germanium atom and four chlorine atoms. It is a colorless to yellow liquid with a pungent odor at room temperature. Germanium tetrachloride is a chloride of germanium and one of the most common and important compounds in germanium chemistry.

Germanium tetrachloride usually exists in the form of liquid, which has a high boiling point and melting point. It is almost insoluble in water, but soluble in many organic solvents such as benzene, toluene, and chlorinated hydrocarbons. In humid air, Germanium tetrachloride will react with water vapor to produce germanic acid.

Germanium chloride is a chloride of germanium, and its preparation methods mainly include the following:

1. Direct Chloride process of germanium chloride: germanium chloride can be prepared by directly reacting germanium with chlorine. Firstly, high-purity germanium metal is placed in a reactor, and then chlorine gas is introduced into the reactor and heated. During the reaction process, germanium reacts with chlorine gas to generate germanium chloride. The reaction equation is as follows: Ge+2Cl2 GeCl4

2. Indirect Chloride process of germanium chloride: indirect Chloride process is to prepare germanium chloride by first preparing Germanate and then chlorinating. First, germanium powder is reacted with dilute sulfuric acid to generate germanic acid: Ge+4H2SO4 Ge (SO4) 2+4H2O. Then, germanic acid is reacted with sodium chloride (NaCl) or Barium chloride (BaCl2) to generate corresponding germanium chloride: Ge (SO4) 2+4NaCl GeCl4+2Na2SO4 Ge (SO4) 2+4BaCl2 GeCl4+2BaSO4

3. Bromination method of germanium chloride: Bromination method is another method for preparing germanium chloride. By reacting germanium with bromine gas under high temperature conditions, a mixture of germanium chloride and germanium bromide can be obtained. Then, separate germanium chloride and germanium bromide by fractionation or other methods.
