Abstract
Antimony pentafluoride is prepared by reacting antimony pentachloride with hydrogen fluoride at 0-100 DEG C. in aluminium apparatus under controlled conditions. Antimony pentafluoride is charged into an aluminium vessel fitted with a reflux condenser kept at -45 DEG or lower and gaseous anhydrous hydrogen fluoride bubbled in. The temperature of the charge is preferably kept at 10 DEG C to 30 DEG in the initial stages, and is allowed to rise to 60 DEG C. to 70 DEG C. for the final stages when the compound SbF5. 5HF formed is believed to decompose. When all hydrochloric acid has been evolved, and after standing, the temperature of the condenser is raised to 12-25 DEG C. and the reaction mass gradually heated, until, at about 140-150 DEG C. all hydrogen fluoride has been boiled off, and antimony pentafluoride is left. This may be purified by distillation from the reaction vessel employing an aluminium condenser. The reaction may be carried out by adding antimony pentachloride to liquid anhydrous hydrogen fluoride.
