Title: Zirconium Sulfate
CAS Registry Number: 14644-61-2
Additional Names: Disulfatozirconic acid
Molecular Formula: O8S2Zr
Molecular Weight: 283.35
Percent Composition: O 45.17%, S 22.63%, Zr 32.19%
Line Formula: Zr(SO4)2
Literature 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 Type: 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).
Toxicity data: 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. |
