Ferric chloride tetrahydrate is an inorganic compound; its formula is FeCl2•4H2O. It is a green crystal that is soluble in water and ethanol. In the preparation process, FeCl2 can be mixed with water, then crystallized and dried to obtain ferric chloride tetrahydrate.
The hydrochloric acid solution of about 27% was prepared with hydrochloric acid with a relative density of 1.18, and then the iron filings were slowly added for reaction.When hydrogen is no longer produced, cool, filter, and add some small iron sheets to prevent the chlorination of ferrous chloride.
It is then heated, evaporated and concentrated into a crystalline film, filtered while it is hot, and the filtrate cools the crystals,Following rapid drying, the ferrous chloride is made crystalline.Anhydrous ferrous chloride can be prepared by the reaction of iron with gaseous hydrogen chloride at 900?.
Fe+ 2HCl= FeCl2+H2?
At temperatures above 12.3? and under oxygen-free conditions?tetrahydrate of ferrous chloride can be obtained by dissolving iron in hydrochloric acid
