By now it should be very clear that the terms “fluoride” and “fluorine” are not mutually exclusive. Not only are they not mutually exclusive, but fluorideisfluorine; every fluoride ion is in fact a fluorine atom. Fluoride is notderived fromfluorine, and is not a fluorinecompound, itisfl...
The source used in the preparation of fluorine is hydrogen fluoride, which is generally obtained either by the action of sulfuric acid, H2SO4, on fluorite, CaF2, or by the processing of apatites and phosphorites. Fluorine is prepared by the electrolysis of molten potassium bifluoride KF · (...
Industrial production of fluorine entails the electrolysis of hydrogen fluoride in the presence of potassium fluoride. This method is based on the pioneering studies by Moissan (see below). Fluorine gas forms at the anode, and hydrogen gas at the cathode. Under these conditions, the potassium fluo...
In many energetic formulations, metals are combined with aggressive oxidizers, such as sodium or potassium perchlorate [15,16], to increase their reaction rate. However, use of such aggressive oxidizers is associated with difficulties in handling and storing energetics. In addition, it is important ...

Compounds of the formula X-C6F4-OH, in which X is chlorine, bromine or iodine, are prepared by treating a compound of the formula C6F5-X with an alkali-metal hydroxide in alcoholic solution. The preferred alkali-metal hydroxide is potassium hydroxide and the preferred alcohol is tertiary ...
and it was not until 1886 that the French chemistHenri Moissanprepared the element by electrolyzing a solution ofpotassiumhydrogen fluoride in hydrogen fluoride. He received the 1906Nobel Prizefor Chemistry for isolating fluorine. The difficulty in handling the element and its toxic properties contribu...
