トリフルオロ鉄(III)

化学的特性鉄フッ化物は鉄Feとフッ素Fが結合してできる化合物で化学式はFeFFeF2などが存在しますこれらは無機化合物の一種でありその特性や用途は多岐にわたりますフッ素は非常に反応性が高い元素であるためこれらの化合物は高い化学的安定性を持ち多くの産業分野で利用されています

化学的特性Iron(III) fluoride is only sparingly soluble in water and insoluble in alcohol and ether. When heated in hydrogen it is reduced to iron(II) fluoride and thence to the metal. In aqueous solution the hydrolysis appears to be very slight ; in the presence of alkali metal fluorides, complex fluorides of types MFeF4, M2FeF5.xH2O and M3FeF6 can be crystallized. The magnetic behaviour of FeF3 is complicated; between 63° and 293°K the susceptibility is field strength dependent. The trihydrate has a magnetic moment μ = 2-25 B.M. at 300°K.

化学性质鉄フッ化物はその組成に応じて異なる物理的および化学的特性を示しますFeF3は黄色から茶色の結晶で高い融点を持ち水には溶けにくい性質を持っています一方FeF2は無色から白い結晶でありFeF3に比べるとやや水に溶けやすいです

使用As catalyst in organic reactions.

一般的な説明IRON (II) FLUORIDE is a green crystalline solid. IRON (II) FLUORIDE is slightly soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. IRON (II) FLUORIDE is used in ceramics.

製造方法This can be prepared by the action of fluorine on the metal, iron(II), or iron(III) chloride or by dehydration of the hydrate (obtained from aqueous solution) by heating in a current of hydrogen fluoride. A convenient laboratory preparation involves the reaction of hydrogen fluoride with anhydrous iron(III) chloride at room temperature : FeCl3+3HF→ FeF3+3HCl When crystallized from aqueous solution (iron(III) "hydroxide" and aqueous hydrofluoric acid) it forms the pale pink 4-hydrate (room temperature evaporation) and the pink 3-hydrate (evaporation by heating).
