Fluor et Chlore – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n
\n
\"\"<\/div>
\n

Fluor<\/h3>\n

Le fluor est l’halog\u00e8ne le plus l\u00e9ger et existe sous forme de gaz diatomique jaune p\u00e2le hautement toxique dans des conditions standard. En tant qu’\u00e9l\u00e9ment le plus \u00e9lectron\u00e9gatif, il est extr\u00eamement r\u00e9actif: presque tous les autres \u00e9l\u00e9ments, y compris certains gaz nobles, forment des compos\u00e9s avec le fluor.

\n

Chlore<\/h3>\n

Le chlore est un gaz jaune-vert \u00e0 temp\u00e9rature ambiante. C’est un \u00e9l\u00e9ment extr\u00eamement r\u00e9actif et un agent oxydant puissant: parmi les \u00e9l\u00e9ments, il a la plus haute affinit\u00e9 \u00e9lectronique et la troisi\u00e8me \u00e9lectron\u00e9gativit\u00e9 la plus \u00e9lev\u00e9e, derri\u00e8re seulement l’oxyg\u00e8ne et le fluor.<\/p>\n<\/div>

Fluor et Chlore – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Fluor<\/a><\/h3>\n

En raison des frais de raffinage du fluor pur, la plupart des applications commerciales utilisent des compos\u00e9s fluor\u00e9s, avec environ la moiti\u00e9 de la fluorite extraite utilis\u00e9e dans la fabrication de l’acier.\u00a0Le reste de la fluorite est converti en fluorure d’hydrog\u00e8ne corrosif en route vers divers fluorures organiques, ou en cryolite, qui joue un r\u00f4le cl\u00e9 dans le raffinage de l’aluminium.\u00a0La plupart des proc\u00e9d\u00e9s commerciaux d’enrichissement de l’uranium (diffusion gazeuse et m\u00e9thode de centrifugation gazeuse) exigent que l’uranium soit sous forme gazeuse. Par cons\u00e9quent, le concentr\u00e9 d’oxyde d’uranium doit d’abord \u00eatre converti en hexafluorure d’uranium, qui est un gaz \u00e0 des temp\u00e9ratures relativement basses.\u00a0Les mol\u00e9cules contenant une liaison carbone-fluor ont souvent une stabilit\u00e9 chimique et thermique tr\u00e8s \u00e9lev\u00e9e;\u00a0leurs principales utilisations sont les r\u00e9frig\u00e9rants, l’isolation \u00e9lectrique et les ustensiles de cuisine, le dernier \u00e9tant le PTFE (t\u00e9flon).<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\n

Chlore<\/a><\/h3>\n

Le chlore est utilis\u00e9 dans la fabrication d’une large gamme de produits de consommation, dont environ les deux tiers sont des produits chimiques organiques tels que le chlorure de polyvinyle (PVC), de nombreux interm\u00e9diaires pour la production de plastiques et d’autres produits finis qui ne contiennent pas l’\u00e9l\u00e9ment. En tant que d\u00e9sinfectant courant, le chlore \u00e9l\u00e9mentaire et les compos\u00e9s g\u00e9n\u00e9rateurs de chlore sont utilis\u00e9s plus directement dans les piscines pour les maintenir hygi\u00e9niques. Bien qu’elle soit peut-\u00eatre mieux connue pour son r\u00f4le dans la fourniture d’eau potable, la chimie du chlore contribue \u00e9galement \u00e0 fournir des mat\u00e9riaux de construction \u00e9conomes en \u00e9nergie, de l’\u00e9lectronique, des fibres optiques, des cellules \u00e0 \u00e9nergie solaire, 93 % des produits pharmaceutiques vitaux, 86 % des compos\u00e9s phytosanitaires, des plastiques m\u00e9dicaux, et beaucoup plus.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
