Chemische Eigenschaften
Tetragonal prisms or needles. Deliquescent in moist air, evolves HCl and becomes dull in dry air. Soluble in H3O (slight hydrolysis) and alcohol. Lower hydrates are formed by heating a stream of HCl. It Liberates HCl on heating in air, and the solubility in water is gradually lost; it reverts to the oxide on calcination. Precipitation of an alcoholic solution with ether or acetone yields dizirconyl chloride Zr aO3Cl a -5HaO, which is sparingly soluble in water. The same compound deposits when a dilute aqueous solution of zirconyl chloride is allowed to stand for a month.
Chemische Eigenschaften
solid
Verwenden
Zirconium dichloride oxide is utilized as a precursor to prepare other zirconium compounds. It is employed in acid dyes, pigment toners and antiperspirants. It finds application as a rubber additive and a fiber treatment agent. It is also used in paint drying, refractories, ceramics and glaze.
Allgemeine Beschreibung
This product is used as a potential green catalyst.
l?uterung methode
Recrystallise the chloride several times from water [Ferragina et al. J Chem Soc, Dalton Trans 265 1986]. Recrystallisation from 8M HCl gives the octahydrate as white needles on concentrating. It is also formed by hydrolysing ZrCl4 with water. After one recrystallisation from H2O, 99+% grade zirconyl chloride had Ag, Al, As, Cd, Cu, Hf, Mg, Na, Sc and V at 20, 1.8, 0.6, 0.6, 0.4, 8.4, 0.4, 2.4, 80 and 3 ppm, respectively. (See above.) METAL-ORGANIC COMPOUNDS This section contains metal-organic compounds as well as ammonium and metal salts of organic acids. (For Introduction see p 445.)
