Method for obtaining isotopically enriched metal lead from monoisotopic tetramethyllead and its purification

Аннотация

The main methods of the synthesis of Pb(CH₃)₄, which is used as a working substance in the process of centrifugal separation of isotopes of lead are considered. The results of experimental studies on the dealkylation of Pb(CH₃)₄ with bromine in the temperature range from -30 °C to 20 °C are given. By infrared and mass spectrometry, chemical and thermal analyses dealkylation products were studied. The scheme of conversion isotopically enriched Pb(CH₃)₄ to metallic lead, including dealkylation of Pb(CH₃)₄ with bromine to lead bromide (II) and its subsequent reduction to metallic lead is suggested. The yield of ²⁰⁸Pb, obtained under this scheme is not less than 97%, its chemical purity is not less than 99.9%. The possibility of using distillation and crystallization methods for further purification of ²⁰⁸Pb from impurities is shown.
