Chloride-ferric chloride properties and producing

Chloride-ferric chloride chemical FeCl3 also called ferric chloride, is black brown crystallization, also have thin sheet, melting point for 282 ℃, boiling point for 315 ℃, soluble in water and have strong water imbibition, can absorb the moisture in the air and ChaoXie. From FeCl3 solution exhalation took six for 6H2O FeCl3, gesso, ferric chloride hexahydrate is orange crystals. Chloride-ferric chloride is a kind of very important physico-chemical process. Often used in sewage disposal, and to remove water of heavy metals and phosphate, Liquid chloride-ferric chloride is drinking water, industrial water, industrial waste, urban sewage and pool water treatment of efficient cheap flocculating agent, has the remarkable precipitation heavy metal and sulfide, decoloring, deodorization, oil removal, sterilizing, phosphorus, such as effectiveness,
In preparing can use:
Tong oxygen method
12FeCl2 + 3O2 = 2Fe2O3 + 8FeCl3
Sodium chlorate oxidation and add hydrochloric acid to provide chloride ion method
FeCl2 + NaClO3 + HCl in = FeCl3 + NaCl + H2O
