|Section2= |Section3= |Section7= |Section8= }} Bromine pentafluoride, BrF5, is an interhalogen compound and a fluoride of bromine. It is a strong fluorination reagent. BrF5 finds use in oxygen isotope analysis. Laser ablation of solid silicates in the presence of bromine pentafluoride releases O2 for subsequent analysis. It is also been tested as an oxidizer in liquid rocket propellants and is used as a fluorinating agent in the processing of uranium. ==Preparation== Bromine pentafluoride was first prepared in 1931 by the direct reaction of bromine with fluorine.〔 This reaction is suitable for the preparation of large quantities, and is carried out at temperatures over with an excess of fluorine: : Br2 + 5 F2 → 2 BrF5 For the preparation of smaller amounts, potassium bromide is used: : KBr + 3 F2 → KF + BrF5 This route yields bromine pentafluoride almost completely free of trifluorides and other impurities.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bromine pentafluoride」の詳細全文を読む スポンサード リンク
