CHROMIUM (III) CHLORIDE Chemical Properties,Uses,Production

Physical Properties

Reddish violet crystals; hexagonal plates; density 2.87g/cm3; melts at 1,152°C; decomposes at 1,300°C; slightly soluble in water. The color of hexahydrates range from light-green to violet; all are hygroscopic; density 1.76 g/cm3; soluble in water and ethanol; insoluble in ether; dilute aqueous solutions are violet in color.

Uses

Chromium(III) chloride is used for chromium plating; as textile mordant; in tanning; as a waterproofing agent; and as catalyst for polymerization of olefins.

Preparation

Chromium(III) chloride hexahydrate may be prepared by treating chromium hydroxide with hydrochloric acid: /> Cr(OH)3 + 3HCl + 3H2O → CrCl3•6H2O The anhydrous chromium(III) chloride may be obtained by heating the hydrated salt CrCl3•6H2O with SOCl2 and subliming the product in a stream of chlorine at 600°C. Alternatively, the red-violet anhydrous chloride can be obtained by passing chlorine gas over a mixture of chromic oxide and carbon:
Cr2O3 + 3C +3Cl2 → 2CrCl3 + 3CO

Reactions

Chromium(III) chloride at elevated termperatures decomposes to chromium( II) chloride and chlorine:
2CrCl3→2CrCl2 + Cl2
Heating with excess chlorine produces vapors of chromium(IV) chloride, CrCl4. The tetrahedral tetrachloride is unstable, and occurs only in vapor phase.
When heated with hydrogen, it is reduced to chromium(II) chloride with the formation of hydrogen chloride:
2CrCl3 + H2→2CrCl2 + 2HCl
Chromium(III) chloride has very low solubility in pure water. However, it readily dissolves in the presence of Cr2+ ion. Reducing agents such as SnCl2 can “solubilize” CrCl3 in water. It forms adducts with many donor ligands. For example, with tetrahydrofuran (THF) in the presence of zinc, it forms the violet crystals of the complex CrCl3•3THF.

Chemical Properties

Chromic chloride is a highly corrosive, Blue or greenish to black crystalline solid.

Uses

Supplement(trace mineral).

Air & Water Reactions

The rate of solution for water is extremely slow, pH of 0.2 M. aqueous solution is 2.4.

Reactivity Profile

When heated to decomposition, CHROMIUM (III) CHLORIDE emits toxic fumes of chlorine containing compounds. Violent reaction with lithium, nitrogen. Incompatible with strong oxidizers. [EPA, 1998].

Hazard

A poison.

Health Hazard

CHROMIUM (III) CHLORIDE displays high dermal toxicity, and moderate oral toxicity.

Safety Profile

Poison by skin contact, inhalation, and intraperitoneal routes. Experimental teratogenic and reproductive effects. Human mutation data reported. Questionable carcinogen. Reacts violently with lithium under nitrogen atmosphere. When heated to decomposition it emits toxic fumes of Cl-.

Potential Exposure

Chromic chloride is used for production of solutions of basic chlorides and as a catalyst for polymerization of olefins and other organic reactions; in chromizing; in the manufacture of chromium metal and compounds; as a textile mordant; in tanning; in corrosion inhibitors; and as a waterproofing agent. A nutritional supplement.

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 respiration 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 running 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. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Shipping

UN1759 Corrosive solids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required. UN1760 Corrosive liquids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.

Purification Methods

Sublime the chloride in a stream of dry HCl. Alternatively, the impure chromic chloride (100g) is added to 1L of 10% aqueous K2Cr2O7 and several millilitres of conc HCl, and the mixture is brought to a gentle boil with constant stirring for 10minutes. (This removed a reducing impurity.) The solid is separated and washed by boiling with successive 1L lots of distilled water until the wash water no longer gives a test for chloride ion, then dry it at 110o [Poulsen & Garner J Am Chem Soc 81 2615 1959, Hein & Herzog in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1338 1965].

Incompatibilities

Reacts with water and strong oxidizers. Contact with strong acids or acid fumes may produce highly toxic chloride fumes. May attack certain steels, causing pitting attack and stress corrosion

Waste Disposal

Precipitate as chromium hydroxide. Dewater the sludge and dispose of the compacted sludge in single-purpose dumps
