General Description
Ferrous chloride is a greenish white crystalline solid. FERROUS CHLORIDE, SOLID(7758-94-3) is soluble in water. FERROUS CHLORIDE, SOLID(7758-94-3) is noncombustible. FERROUS CHLORIDE, SOLID(7758-94-3) is used in sewage treatment, in dyeing of fabrics, and for many other uses.
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)].
Air & Water Reactions
Water soluble.
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.
Potential Exposure
It is used in textile dyeing, metallurgy,
the pharmaceutical industry and sewage treatment.
Fire Hazard
Special Hazards of Combustion Products: Irritating hydrogen chloride fumes may form in fire.
First aid
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respira tion with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with run ning water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves.
Shipping
UN1759 Ferrous chloride, solid, Hazard class: 8;
Labels: 8-Corrosive material. UN1760 Ferrous chloride,
solution, Hazard class: 8; Labels: 8-Corrosive material.
Incompatibilities
Solution attacks metals. Contact with
ethylene oxide may initiate polymerization. Contact with
potassium or sodium forms an impact-sensitive material.

Chemical Properties
Ferrous chloride is a pale greenish salt-like
crystal or power.
Chemical Properties
Greenish-white crystals.
readily oxidized. Soluble in alcohol and water.
Uses
A paramagnetic solid.
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.
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

ChEBI: Iron dichloride is an iron coordination entity.
Flammability and Explosibility
Nonflammable
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.
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.
