바륨 아세테이트 C화학적 특성, 용도, 생산
개요
Barium acetate (Ba(C2H3O2)2) is the salt of barium (II) and acetic acid.화학적 성질
Barium acetate is a white powder, which is highly soluble: at 0 °C, 55.8 g of barium acetate can be dissolved in 100 g of water. It decomposes upon heating into barium carbonate .물리적 성질
White powdery solid; density 2.47g/cm3; decomposes on heating; highly soluble in water (55.8g /100g at 0°C), sparingly soluble in methanol (~1.43 g per liter).용도
Barium acetate is used as a mordant for printing textile fabrics, for drying paints and varnishes and in lubricating oil. In chemistry, it is used in the preparation of other acetates; and as a catalyst in organic synthesis.제조 방법
Barium acetate is generally produced by the reaction of acetic acid with barium carbonate :BaCO3 + 2 CH3COOH → (CH3COO)2Ba + CO2 + H2O
The reaction is performed in solution and the barium acetate crystallizes out. Alternatively, barium sulfide can be used :
BaS + 2 CH3COOH → (CH3COO)2Ba +H2S
Again, the solvent is evaporated off and the barium acetate crystallized.
화학 반응
When heated in air, barium acetate decomposes to the carbonate. It reacts with acids: reaction with sulfuric acid, hydrochloric acid and nitric acid give the sulfate, chloride and nitrate respectively.일반 설명
Barium acetate is the barium salt of acetic acid.위험도
The salt or its aqueous solution is highly toxic. LD10 (oral) rabbit: 236 mg/kg; LD10 (subcutaneous) rabbit: 96 mg/kg. See Barium.Safety Profile
Poison via ingestion, intravenous, and subcutaneous routes. When heated to decomposition it emits acrid smoke and fumes. See also BARIUM COMPOUNDS.Purification Methods
Crystallise the salt twice from anhydrous acetic acid and dry it under vacuum for 24hours at 100o. [Beilstein 2 I 49, 2 II 117, 2 III 192, 2 IV 114.]바륨 아세테이트 준비 용품 및 원자재
