Description and references
Tetrahydrate usually prepd by treating zirconium
oxychloride with hot concd H2SO4: Blumenthal, J. Chem. Educ. 39, 604 (1962).
Toxicity study: Cochran et al., Arch. Ind. Hyg. Occup. Med. 1, 637 (1950).
Derivative
Tetrahydrate.
Properties
Crystalline solid. Converted to monohydrate at
100°; to anhydr form at 380°. Soly in water (18°): 52.5 g/100 g
of soln. A soln at room temp deposits a solid on standing. The more
dilute the soln, the more rapid the deposition. The composition of
the solid is 4ZrO2.3SO3.15H2O, known
as Hauser's salt: Hauser, Herzfeld, Z. Anorg. Allg.
Chem. 67, 369 (1910). This pptn does not take
place if the soln has been heated above 64°. LD50 in rats: 3.5 g/kg orally; 175 mg/kg i.p. (Cochran).Use
Catalyst support; precipitation of amino acids and
proteins; in the tanning industry.
