Синтез, состав, строение бензоилацетонатов переходных металлов и их применение в качестве газохроматографических сорбентов В. А. Немцева, Ж. В. Фаустова

By: Немцева, Валерия АлександровнаContributor(s): Фаустова, Жанна ВладимировнаMaterial type: ArticleArticleOther title: Synthesis, composition and structure of benzoilacetonates of transition metals and the possibility of their use as gaschromatographic sorbents [Parallel title]Subject(s): хроматографические свойства | полярность | элементный анализ | гравиметрический анализ | экспериментальные данные | мезопористые силикагели | газохроматографические сорбенты | бензоилацетонатыGenre/Form: статьи в сборниках Online resources: Click here to access online In: Перспективы развития фундаментальных наук. Т. 2 : сборник научных трудов XV Международной конференции студентов, аспирантов и молодых ученых, 24–27 апреля 2018 г Т. 2 : Химия. С. 219-221Abstract: 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. 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.
