Perfluorobutyl iodide Usage And Synthesis

Description

Perfluorobutyl iodide (PFBI) is a promising alternative to chlorofluorocarbon solvents used in aircraft ground maintenance operations and other military and commercial operations because it cleans well, has zero ozone depletion potential, and has extremely low global warming properties. Perfluorobutyl iodides also could used as gain media for a solar-pumped laser amplifier. This compound is usually utilized as perfluoroalkyl radical precursors[1–3].

Chemical Properties

clear colourless liquid with pungent odour

Uses

Perfluorobutyl Iodide is used as an organocatalyst in some polymerization reactions.

Synthesis

Add 10 mol of triphenylphosphine chloride and 50 mol of N-methylimidazole hydrochloride to methanol and stir to dissolve. Heat to 50°C, add 65 moles of aluminum chloride, stir and dissolve, continue the reaction for 2 hours, raise the temperature to 80°C, evaporate the solvent, and filter to remove the insoluble matter to obtain quaternary ammonium salt and N-alkyl imidazole salt composite aluminum acid. Salt ionic liquid. Add 2 kg of the aluminate ionic liquid prepared in step S1 to the reaction kettle equipped with a reflux device, then add 264 g of perfluoropentanoic acid and raise the temperature to 80°C. Slowly add 2.5 mol of iodine ethanol solution dropwise within 5 hours. After the dropwise addition is completed, heat to 100°C for 8 hours. The reaction solution was allowed to stand and separated into layers to separate the aluminate ionic liquid and product layers. The product layer was purified by distillation to obtain 336g of Perfluorobutyl iodide.
