Mechanistic Study of the Calcination of Supported Chromium(III) Precursors for Ethene Polymerization Catalysts

Temperature-programmed calcination of basic chromium(III) acetate impregnated onto a high surface area silica support and chromium(III) acetylacetonate dry-blended with silica has been studied by quadrupole mass spectrometry and infrared spectroscopy. In both cases the same reactive intermediate has...

Description
Summary:Temperature-programmed calcination of basic chromium(III) acetate impregnated onto a high surface area silica support and chromium(III) acetylacetonate dry-blended with silica has been studied by quadrupole mass spectrometry and infrared spectroscopy. In both cases the same reactive intermediate has been identified.
