베릴륨 황산염, 테트라수화물 C화학적 특성, 용도, 생산
화학적 성질
colourless crystals물리적 성질
Beryllium sulfate is a colorless crystalline solid with a tetragonal crystal system.The tetrahydrate salt loses water of crystallization on heating to about 110°C to form a dihydrate. Upon heating to 400°C, it then forms the anhydrate. Further heating to 550°C causes decomposition of the anhydrate to BeO and SO2 and O2. Beryllium sulfate is soluble in water, tetrahydrate being more soluble in water (30.5 g/100 ml at 30°C) than the anhydrous salt; both are insoluble in alcohol.용도
In Industries it is used for beryllium salt making, ceramics and chemical reagents.제조 방법
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. The anhydrate may also be prepared by reacting the oxide with SO2 gas at elevated temperature. Its CAS number is 13510-49-1. If the solution method is used, a tetrahydrate forms, (BeOH)2SO4·4H2O whose molecular weight is 177.1462 g/mol with a CAS number of 7787-56-6.No major commercial application of berylliumsulfate is known and it has not been offered for sale.
정의
ChEBI: A hydrate of beryllium sulfate containing beryllium (in +2 oxidation state), sulfate and water moieties in the ratio 1:1:4.일반 설명
White crystalline solid. Sinks in water and dissolves. Odorless. Highly toxic by inhalation and ingestion.공기와 물의 반응
Water soluble.반응 프로필
Salts, basic, such as BERYLLIUM SULFATE TETRAHYDRATE are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Incompatible with acids.화재위험
Literature sources indicate that BERYLLIUM SULFATE TETRAHYDRATE is probably nonflammable.Safety Profile
Confirmed carcinogen withexperimental carcinogenic data by inhalation. Deadlypoison by subcutaneous and intravenous routes. Humanmutation data reported. When heated todecomposition it emits very toxic fumes of BeO and SOx.Purification Methods
It crystallises from weak aqueous H2SO4 and is dried in air.베릴륨 황산염, 테트라수화물 준비 용품 및 원자재
