Hazard Information | Back Directory | [General Description]
White lustrous crystalline solid. Used as a source of pure zirconium, as a tanning agent, in analytical chemistry and in treating textiles. ZIRCONIUM TETRACHLORIDE(10026-11-6) is decomposed by water. Corrosive to metals in the presence of moisture and to tissue. | [Reactivity Profile]
ZIRCONIUM TETRACHLORIDE is corrosive to metals in the presence of moisture and to tissue. Behavior in Fire: Will not burn-sublimes above 626°F (331°C). May give off HCl fumes [USCG, 1999]. ZIRCONIUM TETRACHLORIDE is incompatible with alcohols (ethanol), lithium metal, and tetrahydrofuran. | [Air & Water Reactions]
Reacts vigorously with water forming hydrochloric acid with the evolution of heat. | [Health Hazard]
INHALATION: Irritating to upper respiratory tract; presumably caused by liberated HCl. EYES: Irritating. SKIN: Irritating. INGESTION: Burning pain in the mouth and throat, vomiting, watery or bloody diarrhea, retching, collapse, and convulsions. | [Fire Hazard]
Behavior in Fire: Will not burn-sublimes above 626°F (331°C). May give off HCl fumes. | [Chemical Properties]
White, lustrous crystals. Sublimes
above 300C. Soluble in alcohol; decomposes in
water. | [Chemical Properties]
Zirconium tetrachloride forms lustrous, white, monoclinic
crystals that melt at 437 ℃. It is a corrosive powder. It is
hygroscopic, and thus soluble in cold water, alcohol, ether,
and concentrated hydrochloric acid. It reacts vigorously with
water forming hydrogen chloride (irritating vapor) and zirconium
oxychloride. When moist, zirconium tetrachloride
reacts with common materials to form hydrochloric acid that
is corrosive to many metals. Through hydrolysis to HCl,
zirconium tetrachloride can irritate the respiratory tract and
other superficial surfaces of the body on exposure.
Zirconium tetrachloride readily forms coordinate bonds with
oxygen and nitrogen in organic molecules. | [Physical properties]
White monoclinic crystals; hygroscopic; density 2.80 g/cm3; sublimes at 331°C; triple point 437°C; vapor pressure 1 torr at 190°C; critical temperature 504.85°C; critical pressure 56.95 atm; critical volume 319 cm3/mol; decomposed by water; soluble in alcohol, ether, and concentrated hydrochloric acid. | [Uses]
For applications in organozirconium chemistry.
1. Activates pyrrolidines for improved conversion, via a modified Bouveault reaction, to the corresponding α,α-dimethylamines.
2. Zirconium (IV) chloride is used as an efficient catalyst in the Pechmann condensation reaction of phenols with β‐keto esters leading to the formation of coumarin derivatives in good yields under solvent‐free conditions.
| [Uses]
Friedel-Crafts catalyst. Component of Ziegler-type catalysts in the condensation of ethylene. Starting material in the synthesis of a number of organic derivatives of zirconium, such as alkoxides and zircocene. The alkoxides have been shown to be of value in the curing of silicone plastic films. The alkoxyzirconium carboxylates are said to be useful in the water-repellent treatment of textiles and other fibrous materials. | [Uses]
Zirconium(IV) chloride (ZrCl4) is a Lewis acid catalyst, which has low toxicity. It is a moisture resistant material that is used as a catalyst in organic transformations.
ZrCl4 can be used as a catalyst for a variety of organic syntheses, such as Friedel-Crafts reaction, condensation reaction and other reduction reactions.
| [Definition]
ChEBI: A zirconium coordination entity comprising four chlorine atoms bound to a central zirconium atom. | [Preparation]
Zirconium tetrachloride is obtained as an intermediate in recovering zirconium metal from zircon and other minerals (See Zirconium, Recovery). The tetrachloride is obtained by heating a mixture of zirconium hydroxide and car 1004 bon with chlorine gas Also, tetrachloride can be made by reacting zirconium hydroxide with hydrochloric acid: Zr(OH)4 + 4HCl → ZrCl4 + 4H2O. | [Flammability and Explosibility]
Nonflammable | [Purification Methods]
Crystallise it repeatedly from conc HCl. It is hydrolysed by H2O to form white ZrOCl2 (see below) and HCl. [Krebs Z Anorg Allgem Chem 378 263 1970.] |
