Ferrous chloride Chemical Properties,Uses,Production

Occurrence and Uses

Iron(II) chloride occurs in nature as the mineral lawrencite. Iron dichloride is used as a mordant for dyeing; and as a reducing agent. It also is used in pharmaceutical preparation; in sewage treatment; and in metallurgy.

Physical Properties

White hexagonal crystal; hygroscopic; density 3.16g/cm3; melts at 677°C; vaporizes at 1,023°C; vapor pressure 20 torr at 737°C and 200 torr at 897°C; highly soluble in water, ethanol and acetone; slightly soluble in benzene. The dihydrate and tetrahydrate are greenish monoclinic crystals; densities 2.39 and 1.39 g/cm3, respectively; decomposing at 120 and 105°C, respectively; both the hydrates soluble in water.

Preparation

Iron(II) chloride is prepared by passing chlorine or hydrogen chloride gas over iron at red heat or 700°C:
Fe + 2HCl → FeCl2 + H2
Fe + Cl2 → FeCl2
It also may be produced by the reduction of iron(III) chloride with hydrogen or other reducing agents at elevated temperatures:
2FeCl3 + H2 → 2FeCl2 + 2HCl
The tetrahydrate is obtained by dissolving the metal in hydrochloric acid followed by crystallization at room temperature.
Fe + 2HCl + 4H2O → FeCl2•4H2O + H2
The tetrahydrate gradually loses water when heated above 105°C forming dihydrate, monohydrate and the anhydrous salt. At 220°C it loses all its water of crystallization.

Description

Ferrous chloride is a pale greenish salt-likecrystal or power. Molecular weight = 126.75; Specific gravity (H2O:1) = 1.93 at 20 C; Boiling point=1012 C;Freezing/Melting point = 675.8 C. Hazard Identification(based on NFPA-704 M Rating System): Health 3,Flammability 0, Reactivity 1. Soluble in water.

Chemical Properties

Greenish-white crystals. readily oxidized. Soluble in alcohol and water.

Chemical Properties

Ferrous chloride is a pale greenish salt-like crystal or power.

Physical properties

White hexagonal crystal; hygroscopic; density 3.16g/cm³; melts at 677°C;vaporizes at 1,023°C; vapor pressure 20 torr at 737°C and 200 torr at 897°C;highly soluble in water, ethanol and acetone; slightly soluble in benzene. Thedihydrate and tetrahydrate are greenish monoclinic crystals; densities 2.39and 1.39 g/cm³, respectively; decomposing at 120 and 105°C, respectively;both the hydrates soluble in water.

Uses

A paramagnetic solid.

Uses

Used in the synthesis of a novel cis-Fe(BPE5)2Cl2 (BPE5=1,2-diphospholanoethane) complex, which has potential application in many types of reactions such as intra- or intermolecular activation.1

Uses

Ferrous chloride (FeCl2) is used in pharmaceutical preparations, for sewage treatment, and as a mordant (which fixes dyes so that they will not run) in textiles.

Preparation

Iron(II) chloride is prepared by passing chlorine or hydrogen chloride gasover iron at red heat or 700°C:
Fe + 2HCl → FeCl₂ + H₂
Fe + Cl₂ → FeCl₂
It also may be produced by the reduction of iron(III) chloride with hydrogenor other reducing agents at elevated temperatures:
2FeCl₃ + H₂ → 2FeCl₂ + 2HCl
The tetrahydrate is obtained by dissolving the metal in hydrochloric acidfollowed by crystallization at room temperature.
Fe + 2HCl + 4H₂O → FeCl₂•4H₂O + H2
The tetrahydrate gradually loses water when heated above 105°C formingdihydrate, monohydrate and the anhydrous salt. At 220°C it loses all its waterof crystallization.

Definition

ChEBI: Iron dichloride is an iron coordination entity.

General Description

Ferrous chloride is a greenish white crystalline solid. Ferrous chloride is soluble in water. Ferrous chloride is noncombustible. Ferrous chloride is used in sewage treatment, in dyeing of fabrics, and for many other uses.

Air & Water Reactions

Water soluble.

Reactivity Profile

Alkali metal hydroxides, acids, anhydrous chlorides of iron, tin, and aluminum, pure oxides of iron and aluminum, and metallic potassium are some of the catalysts that may cause ethylene oxide to rearrange and polymerize, liberating heat, [J. Soc. Chem. Ind. 68:179(1949)]. Explosions occur , although infrequently, from the combination of ethylene oxide and alcohols or mercaptans, [Chem. Eng. News 20:1318(1942)].

Health Hazard

Inhalation of dust irritates nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes and may cause skin irritation on prolonged contact.

Fire Hazard

Special Hazards of Combustion Products: Irritating hydrogen chloride fumes may form in fire.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by ingestion and intraperitoneal routes. Mutation data reported. Corrosive. Probably an irritant to the eyes, skin, and mucous membranes. Can react violently with ethylene oxide, K, Na. di%en heated to decomposition it emits toxic fumes of Cl-. See also CHLORIDES and IRON.

Potential Exposure

It is used in textile dyeing, metallurgy, the pharmaceutical industry and sewage treatment.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water ormilk. Do not induce vomiting.Note to physician: For severe poisoning do not use BAL[British Anti-Lewisite, dimercaprol, dithiopropanol(C3H8OS2)] as it is contraindicated or ineffective in poisoning from iron.

storage

Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with this chemical you should be trained on itsproper handling and storage. Store in tightly closed containers in a cool, well-ventilated area away from potassium,sodium metals, or ethylene oxide.

Shipping

UN1759 Ferrous chloride, solid, Hazard class: 8; Labels: 8-Corrosive material. UN1760 Ferrous chloride, solution, Hazard class: 8; Labels: 8-Corrosive material.

Purification Methods

It forms white hygroscopic rhombohedral crystals with a green tint which oxidise in air to FeCl3 and Fe2O3. It is soluble in H2O, EtOH Me2CO but insoluble in Et2O. The tetrahydrate is pale green to pale blue in colour and loses 2H2O at 105-115o. The dihydrate loses H2O at 120o. [Anhydrous FeBr2 can be obtained by carefully dehydrating the tetrahydrate in a stream of HBr and N2, and it can be sublimed under N2.] The ferrous iron in aqueous solutions of these salts readily oxidises to ferric iron. (See above.) [Kovacuumic & Brace Inorg Synth VI 172 1960, Lux in Handbook of Preparative Inorganic Chemistry (Ed Brauer) Academic Press Vol II p 1491 1965.]

Incompatibilities

Solution attacks metals. Contact with ethylene oxide may initiate polymerization. Contact with potassium or sodium forms an impact-sensitive material.
