Synthesis, composition and structure of benzoilacetonates of transition metals and the possibility of their use as gaschromatographic sorbents

The aim of the work was to obtain and study chelate complexes of benzoylacetonates of transition metals, to study their chromatographic properties by the example of mesoporous silica gel modified with benzoylacetonates Co, Ni, Си, and to establish a correlation between the composition, structure and properties of the materials obtained. To study the physicochemical properties of the complexes and sorbents obtained, modem equipment was used. The composition of the synthesized metal chelate complexes was studied by IR, atomic-emission spectroscopy, gravimetric and elemental analyzes. Chromatographic studies were performed on a gas chromatograph MAESTRO 7820 (Agilent Technologies) with a flame ionization detector. In this work we used metal filled columns 1 m long and inner diameter 3 mm
