ビス酢酸ニッケル(II) 化学特性,用途語,生産方法
説明
Nickel (II) acetate (Ni (CH
3 COO)
2 ) is an inorganic compound of nickel and acetic acid. This inorganic compound is usually found as the tetrahydrate. It is used for electroplating.
It can be made by reacting nickel or nickel (II) carbonate with acetic acid.

The green tetrahydrate has been determined by X-ray crystallography to be octahedral about the central nickel atom, coordinated by four water molecules and two acetate fragments.It may be dehydrated in vacuo, by reaction with acetic anhydride,or by heat.
化学的特性
Green, monoclinic crystals; effloresces
somewhat in air.Soluble in water and alcohol.
物理的性質
The tetrahydrate is a green crystalline solid; sweet taste; odor of acetic acid; density 1.744 g/cm
3; loses water on heating to form a yellow-green powder of anhydrous nickel acetate; decomposes above 250°C; soluble in water, 17g/100mL at 20°C; sparingly soluble in alcohol.
使用
Textiles (mordant), catalyst.
一般的な説明
Dull green odorless solid. Sinks and mixes slowly with water.
空気と水の反応
Water soluble.
反応プロフィール
Nickelous acetate is a green, crystalline material, mildly toxic and carcinogenic. Combustible when exposed to heat or flame. When heated to decomposition Nickelous acetate emits acrid smoke and irritating fumes [Lewis, 3rd ed., 1993, p. 909].
危険性
Toxic by ingestion, a carcinogen (OSHA).
健康ハザード
Inhalation causes irritation of nose and throat. Ingestion causes vomiting. Contact with eyes causes irritation. May cause dermatitis in contact with skin.
安全性プロファイル
Confirmed carcinogen
with experimental neoplastigenic and
tumorigenic data. Poison by ingestion,
intraperitoneal, and subcutaneous routes.
Experimental reproductive effects. Mutation
data reported. When heated to
decomposition it emits irritating fumes. See
also NICKEL COMPOUNDS.
安全性
Nickel salts are carcinogenic and irritate the skin.
