METHOD FOR PRODUCING ISOTOPICALLY ENRICHED GERMANIUM TETRACHLORIDE Russian patent published in 2023 - IPC C01G17/04 C01B9/02 

FIELD: inorganic chemistry.

SUBSTANCE: production of isotopically enriched germanium tetrachloride GeCl₄. Method for producing isotopically enriched germanium tetrachloride from inorganic compounds is proposed, characterized by that isotopically enriched germanium tetrafluoride (⁷⁰GeF₄, ⁷²GeF₄, ⁷³GeF₄, ⁷⁴GeF₄, ⁷⁶GeF₄ ) and aluminium chloride (III) are used as inorganic compounds, the interaction of which is carried out at a temperature of 150-400°C in a closed reactor with a 2-10-fold excess of aluminium (III) chloride relative to the stoichiometric ratio and the contact time of the reagents of 2-20 hours.

EFFECT: proposed method makes it possible to increase the yield of isotopically enriched germanium tetrachloride up to 95% and to reduce the content of impurities in the resulting product.
