It is an industrial scale commodity chemical compound, with the formula Fe Cl 3 and with iron in the +3 oxidation state.
When dissolved in water, iron(III) chloride undergoes hydrolysis and gives off heat in an exothermic reaction. The resulting brown, acidic, and corrosive solution is used as a flocculant in sewage treatment and drinking water production, and as an etchant for copper-based metals in printed circuit boards. Anhydrous iron(III) chloride is a fairly strong Lewis acid, and it is used as a catalyst in organic synthesis. Iron(III) chloride is used as catalyst for the reaction of ethylene with chlorine, forming ethylene dichloride (1,2-dichloroethane), an important commodity chemical, which is mainly used for the industrial production of vinyl chloride, the monomer for making PVC. Manganese(II) chloride. Cobalt(II) chloride. Ruthenium(III) chloride. Iron(III) chloride, generically called ferric chloride, is the chemical compound with the formula FeCl. Anhydrous iron(III) chloride is a fairly strong Lewis acid, and it is used as a catalyst in organic synthesis. Iron(III) chloride is also used as a catalyst for the reaction of ethylene with chlorine, forming ethylene dichloride (1,2-Dichloroethane), an important commodity chemical, which is mainly used for the industrial production of vinyl chloride, the monomer for making PVC. The substance decomposes on contact with water producing hydrogen chloride. The solution in water is a medium strong acid. Reacts violently with alkali metals, allyl chloride, ethylene oxide, styrene and bases causing explosion hazard. Attacks metal forming flammable/explosive gas (hydrogen-see ICSC0001) . OCCUPATIONAL EXPOSURE LIMITS: TLV: (soluble iron salts, as Fe) 1 mg/m 3; (ACGIH 2004). 1 Ferric Chloride (iron perchloride, FeCl3) and Copper in a 42 baume solution will etch a densely crosshatched area pretty well in one to 3 hours. 2  An aquatint can be etched in 5 to 60 minutes. 3  Dutch Mordant (potassium chlorate, KClO3 and hydrochloric acid) is also used to etch copper.  Iron(III) chloride, also called ferric chloride, is an industrial scale commodity chemical compound, with the formula Fe Cl 3 and with iron in the +3 oxidation state.

Iron(III) chloride is used as catalyst for the reaction of ethylene with chlorine, forming ethylene dichloride (1,2-dichloroethane), an important commodity chemical, which is mainly used for the industrial production of vinyl chloride, the monomer for making PVC. The mixture is filtered before use. The organic substance is dissolved in water, methanol or ethanol, then the neutralised iron(III) chloride solution is added—a transient or permanent coloration (usually purple, green or blue) indicates the presence of a phenol or enol. Iron(III) chloride is used as catalyst for the reaction of ethylene with chlorine, forming ethylene dichloride (1,2-dichloroethane), an important commodity chemical, which is mainly used for the industrial production of vinyl chloride, the monomer for making PVC. 3 is treated with hydroxide ion to form a floc of iron(III) hydroxide (more correctly formulated as FeO(OH)) that can remove suspended materials. 3 solution is added—a transient or permanent coloration (usually purple, green or blue) indicates the presence of a phenol or enol. Iron(III) chloride is also used as a catalyst for the reaction of ethylene with chlorine, forming ethylene dichloride (1,2-Dichloroethane), an important commodity chemical, which is mainly used for the industrial production of vinyl chloride, the monomer for making PVC.
