Abstract

A possibility to use exchange reaction of metal \-diketonates and the vapours of \-diketones for the separation of volatile \-diketonate complexes by the method of fractional sublimation has been studied. When a mixture of thenoyltrifluoroacetonates of95Zr−95Nb and Th−233Pa is treated with a carrier gas containing hexafluoroacetylacetone vapours, zirconium and thorium, unlike niobium and protactinium, form volatile hexafluoroacetyl-acetonates which sublimate quite completely at 115°C. Niobium and protactinium remain in the initial sample in the form of nonvolatile compounds.
