manufacture of iron iii chloride.

摘要

A method for preparing anhydrous ferric chloride from a hydrous solution containing ferric chloride that possibly contains organic substances and or ferrous chloride, comprises the steps of: a) removing water from a ferric-chloride water solution, or a solution in which at least a portion of the ferrous chloride has possibly been converted by oxidation into ferric chloride, by drying in an atmosphere containing hydrochloric acid; and b) refining the anhydrous ferric chloride by sublimating it into the gas phase in a chlorine-containing atmosphere and by subliming it into pure crystalline ferric chloride. i
