Vaporization and pyrolysis of uranyl β-diketonates

For the group of uranyl β-diketonates with aliphatic and aromatic periphery radicals the temperatures of condensed phase transformations as a result of heating in an inert atmosphere and characteristics of mass transfer process in vacuum have been determined for the first time by the methods of DTA and sublimation analysis. A relation between thermal characteristics of the substances and completeness of mass transfer is detected; dependence of the ability of uranyl β-diketonates for reversible vaporization on the structure of organic ligands is found
