Mechanically activated mixtures of calcium chloride with sodium beta-diketonates

The preparative chemical method, X-ray diffraction analysis, and vacuum sub limation method are used to show that the mechanical treatment of mixtures of calcium chloride with sodium salts of acetylacetone, trifluoroacetylacet one, dipivaloylmethane, or acetylacetoimine induces their interaction, form ing volatile calcium beta -diketonates and sodium chloride. Heating of the reaction mixtures results in sublimation of the obtained calcium beta -dike tonate and nonreacted sodium beta -diketonate; this is impeded by the forma tion of poorly volatile forms.
