Gas Phase Chromatography of Metal Chelates of Acetylacetone, Trifluoroacetylacetone, and Hexafluoroacetylacetone
The gas phase chromatography of metal chelates of acetylacetone, trifluoroacetylacetone, and hexafluoroacetylacetone was investigated. Chelates of the fluorinecontaining BETA -diketones are more volatile and can be eluted at much lower column temperatures than corresponding complexes of acetylacetone. Tri fluoroacetylacetonato complexes of Be(II), Al(III), In(III), Cr(III), Fe(III), Cu(II), Rh(III), Zr(IV), and Hf(IV) were successfully eluted in the gas phase. Separations of multi-component mixtures of chelates were rapid and efficient. Geometrical isomers of Cr(III) trifluoroacetylacetonate were separated by gasliquid chromatography. The separation of optical isomers by gas-- liquid and gas-- solid chromatography is discussed.
