Specific features of the separation of inorganic and organic compounds on alumina modified with fluorinated polyimide

Highly fluorinated thermally stable polyimide is synthesized and used to modify alumina. The effects of polyimide concentration (10 and 15 wt %) and thermal treatment conditions on the adsorption and chromatographic properties of the prepared adsorbents are studied by the low-temperature adsorption...

Summary:Highly fluorinated thermally stable polyimide is synthesized and used to modify alumina. The effects of polyimide concentration (10 and 15 wt %) and thermal treatment conditions on the adsorption and chromatographic properties of the prepared adsorbents are studied by the low-temperature adsorption of nitrogen and gas chromatography on packed columns. The adsorbents prepared possess mesoporous structures and ensure the selective separation of permanent gases and hydrocarbons on their simultaneous presence.
