Ferrous chloride is prepared by addition of iron powder to a solution of hydrochloric acid in methanol. This reaction gives the methanol solvate of the dichloride, which upon heating in a vacuum at about 160 °C converts to anhydrous FeCl2. The net reaction is shown: Fe + 2 HCl → FeCl2 + H2 FeBr2 and FeI2 can be prepared analogously.
