6. Ferric chloride production
A distinction must be made between the production of anhydrous FeCl3 and hydrated FeCl3, produced and sold as a concentrated solution.
6.1 Anhydrous ferric chloride
Direct synthesis is achieved by direct attack of clean, unpolluted scrap metal with chlorine in slight excess to avoid the formation of non-volatile FeCl2, an intermediate compound remaining in the reactor.
The reaction takes place between 500 and 700°C, with scrap metal preheated and fed in continuously or batchwise. FeCl3 vapors are discharged to air- or water-cooled wall chambers, where they condense. The FeCl3 crystals...
