Specification
The Ferric fluoride is an organic compound with the formula F3Fe. The IUPAC name of this chemical is trifluoroiron. With the CAS registry number 7783-50-8, it is also named as Ferric fluoride, anhydrous. The product's category is Inorganics. Besides, it is a green powder, which should be stored in a cool and dry place.
Physical properties about Ferric fluoride are: (1)Enthalpy of Vaporization: 25.54 kJ/mol; (2)Boiling Point: 19.5 °C at 760 mmHg; (3)Vapour Pressure: 922 mmHg at 25°C.
Preparation: this chemical is prepared by treating virtually any anhydrous iron compound with fluorine. More practically and like most metal fluorides, it is prepared by treating the corresponding chloride with hydrogen fluoride:
FeCl3 + 3 HF → 2 FeF3 + 3 HCl
Uses of Ferric fluoride: the primary commercial use of Ferric fluoride is in the production of ceramics. Ferric fluoride has also been shown to catalyze chemoselective addition of cyanide to aldehydes to give the cyanohydrins.
When you are using this chemical, please be cautious about it as the following:
It is harmful by inhalation, in contact with skin and if swallowed. Please take off immediately all contaminated clothing. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Besides, this chemical can cause burns. When you are using it, wear suitable gloves and eye/face protection and do not breathe dust. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible).
