| | Barium acetate Usage And Synthesis |
| Description | Barium acetate (Ba(C2H3O2)2) is the salt of barium (II) and acetic acid. | | Chemical Properties | White Crystalline Powder | | Chemical Properties | 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 . | | Physical properties | 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). | | Uses | Barium acetate [Ba(C2H3O2)2H2O], a white crystal, is used as a dryer for paints and varnishes.
It is produced by adding acetic acid to barium sulfate and recovering the crystals by
evaporation. It is also used as a textile mordant and catalyst. | | Uses | Used as catalyst for organic reactions | | Uses | 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. | | Preparation | 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. | | Definition | ChEBI: Barium acetate is an acetate salt in which the cationic component is barium(2+). It has a role as a mordant and a catalyst. It is an organic barium salt and an acetate salt. | | Reactions | 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. | | General Description | Barium acetate is the barium salt of acetic acid. | | Hazard | The salt or its aqueous solution is highly toxic. LD10 (oral) rabbit: 236 mg/kg; LD10 (subcutaneous) rabbit: 96 mg/kg. See Barium. | | Flammability and Explosibility | Not classified | | reaction suitability | core: 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.] |
