硫酸ベリリウム 化学特性,用途語,生産方法
化学的特性
Colorless crystals. Soluble in water; insoluble in alcohol.
物理的性質
Colorless crystalline solid; tetragonal crystal system; hygroscopic; density 2.50 g/cm
3 (tetrahydrate 1.71 g/cm
3); tetrahydrated salt loses water of crystallization on heating; further heating to 550°C causes decomposition; soluble in water, tetrahydrate more soluble in water (30.5g/100g at 30°) than the anhydrous salt; insoluble in alcohol.
使用
No major commercial application of beryllium sulfate is known.
製造方法
Beryllium sulfate may be prepared by treating an aqueous solution of any beryllium salt with sulfuric acid, followed by evaporation of the solution and crystallization. The hydrated product may be converted to anhydrous salt by heating at 400°C.
定義
ChEBI: A metal sulfate in which the metal is beryllium (in the +2 oxidation state) and the ratio of beryllium to sulfate is 1:1.
一般的な説明
Colorless, odorless crystals. Highly toxic by inhalation and ingestion. Sinks and mixes with water.
空気と水の反応
Soluble in water.
反応プロフィール
BERYLLIUM SULFATE is incompatible with the following: Acids, caustics, chlorinated hydrocarbons, oxidizers, molten lithium .
危険性
A confirmed carcinogen.
健康ハザード
Any dramatic, unexplained weight loss should be considered as possible first indication of beryllium disease. Other symptoms include anorexia, fatigue, weakness, malaise. Inhalation causes pneumonitis, nasopharyngitis, tracheobronchitis, dyspnea, chronic cough. Contact with eyes causes conjunctival inflammation. Contact with skin causes dermatitis of primary irritant or sensitization type; causes ulcer formation when in contact with cuts.
火災危険
Special Hazards of Combustion Products: Toxic beryllium oxide and sulfuric acid fumes may form in fire.
安全性プロファイル
