Синтез, состав, строение бензоилацетонатов переходных металлов и их применение в качестве газохроматографических сорбентов

Abstract

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, Cu, 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, modern 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. Results: Sorbents based on mesoporous silica gel modified by intracomplex compounds of benzoylacetonates of cobalt, nickel and copper were obtained. The parameters of gas-chromatographic retention of various classes of organic compounds are determined.
