化学的特性
Zirconium oxychloride exists as white silky crystals, soluble
in water and alcohol. With water, the octahydrate is formed
as tetragonal white needles. It is extremely hygroscopic
and decomposes to zirconium tetrachloride (ZrCl4) and zirconium oxide (ZrO2) at 250 C. It is also formed as the
octahydrate [13520-92-8] as white, tetrahedral crystals that
are very soluble in water, ethyl alcohol, ether, and methanol,
among others, but only slightly soluble in hydrochloric acid.
When heated to decomposition, it emits toxic fumes of
hydrogen chloride.
使用
Textile, cosmetic and grease additive, antiperspirant,
water repellents, chemical reagent, zirconium
salts, in lakes and toners of acidic and basic
dyes, oil-field acidizing aid.
反応プロフィール
Acidic salts, such as Zirconium oxychloride, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
健康ハザード
Has only a mild pharmacological action. Inhalation of dust may irritate nose and throat. Contact with eyes or skin causes irritation.
安全性プロファイル
Poison by
intraperitoneal route. Moderately toxic by
ingestion and subcutaneous routes.
Questionable carcinogen with experimental
neoplastigenic data. When heated to
decomposition it emits toxic fumes of Cl-.
Used as an antiperspirant. See also
ZIRCONIUM COMPOUNDS and
CHLORIDES.
純化方法
Crystallise it repeatedly from 8M HCl to give ZrOCl2.8H2O (see below). On drying, ZrOCl2.6H2O, m 150o, is formed. The product is not free from hafnium. [Blumenthal J Chem Ed 39 607 1962.]
