Ferric chloride tetrahydrate is a kind of inorganic compoundthe formula is FeCl2•4H2O.It is a white crystal that is soluble in water and ethanol.In the preparation process, FeCl2 can be mixed with water,then crystallization and drying to obtain ferric chloride tetrahydrate.

Ferrous  chloride  tetrahydrate uses:

Ferric chloride tetrahydrate is widely used in many chemical reactions:

Used for the preparation of ferric chloride and other compounds.

For the preparation of other metal salts, such as cobalt chloride, nickel chloride, etc.

It is used in the preparation of dyeing agent, strengthening of paper and sewage treatment.

Used as chemical reagent, industrial catalyst and water treatment agent.

Used as educing agent, sewage treatment, detection of selenium.

Also used for agate dyeing, chemical catalyst, mordant, metallurgical plating.

Production method of ferric chloride tetrhydrate

1.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↑

2.At temperatures above 12.3℃ and under oxygen-free conditionstetrahydrate of ferrous chloride can be obtained by dissolving iron in hydrochloric acid.
