Description

Application

A versatile fluoride ion source used in a study of ion-specific swelling and de-swelling of ampholytic polymer gels, in the room temperature oxidation of noble metals in HF, and in the measurement of electronic polarizabilities of ions in polymers of alkali halides.

Potassium fluoride may be employed for doping the natural calcium phosphate (NP) for high yield synthesis of activated alkenes.

General description

Potassium fluoride (KF) on activated alumina is a highly reactive catalyst (basic in nature) for various organic reactions. High reactivity is due to the formation of potassium hexafluoroaluminiate, potassium hydroxide and potassium aluminate on the interaction of its fluoride ion with alumina. Celite coated with potassium fluoride has been proposed as a useful reagent for the hydrogen-bond-assisted reactions. Potassium fluoride on basic alumina in acetonitrile with ultrasound has been employed for the deprotection of tert-butyldimethylsilyl ethers of phenols.
