Abstract

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.
