  • Method for preparing ferric chloride
    Patent number: 5250276
    Abstract: A method for preparing anhydrous ferric chloride from a hydrous solution containing ferric chloride that contains organic substances and/or ferrous chloride. In the method, water is removed from a ferric-chloride water solution or a solution, in which at least a portion of the ferrous chloride has been converted by oxidation into ferric chloride, by drying in an atmosphere containing hydrochloric acid. The anhydrous ferric chloride is refined by sublimating it into gas phase in a chlorine-containing atmosphere and by subliming it into a pure crystalline ferric chloride.
