• Titration with sodium or potassium fluoride yields the exothermic precipitation of an insoluble alumino-fluoride salt.
• 1-Bromohexane undergoes reactions expected of simple alkyl bromides. It can form Grignard reagents. It reacts with potassium fluoride to give the corresponding fluorocarbons.
• HFB is prepared by the action of sulfur tetrafluoride on acetylenedicarboxylic acid or by the reaction of potassium fluoride (KF) with hexachlorobutadiene.
• Potassium fluoride is used for the conversion of chlorocarbons into fluorocarbons. Such reactions usually employ polar solvents such as dimethyl formamide, ethylene glycol, and dimethyl sulfoxide.
• They can also be made by heating the corresponding perchloroaromatic compound with potassium fluoride at high temperature (typically 500 °C), during which the chlorine atoms are replaced by fluorine atoms.

• On a laboratory scale, sulfuryl fluoride has been conveniently prepared from 1,1'-sulfonyldiimidazole, in the presence of potassium fluoride and acid.
• In some countries, table salt is treated with potassium fluoride to enhance dental health.
• The chlorine atom in the 4-chlorobutylsulfonate anion can be substituted by heating with inorganic (e.g. potassium fluoride) or organic salts (e.g. sodium acetate) by the respective anion.
• The dimer is also produced in a reaction with hexafluoropropene and sulfur with some potassium fluoride.
• SF3SF can be made in the laboratory when low pressure (10mm) SCl2 vapour is passed over potassium fluoride or mercuric fluoride heated to 150 °C.

• In 1965 "N"-benzoyl-"N"′-phenylurea was synthesized when dry "N"-chlorobenzamide was reacted with phenylisocyanate or refluxed in dry benzene with anhydrous potassium fluoride.
• In 1886, French chemist Henri Moissan, later a Nobel Prize winner, succeeded in making elemental fluorine by electrolyzing a mixture of potassium fluoride and hydrogen fluoride.
• The Griesheimer process employing the reaction of potassium fluoride with calcium carbide was also used to produce potassium.
