Bismuth(Iii) Acetate (Metals Basis) - Reference Information
| Overview | bismuth acetate also known as bismuth acetate, chemical formula Bi(C2H3O2)3. Molecular weight 386.12. White crystals, like Mica thin slice. Soluble in acetic acid, insoluble in water. Acetic acid is lost by decomposition upon exposure to air and is decomposed more rapidly upon heating. Preparation Method: from bismuth carbonate mannitol solution with glacial acetic acid boiling reflux for 2 hours. Purposes: astringents and preservatives, can also be used for pharmaceutical. |
| major properties | bismuth acetate is hydrolyzed with water to produce bismuth oxyacetate. Bismuth acetate can be used as a catalyst for ring-opening polymerization of glycolide, and its catalytic activity is slightly higher than stannous octoate, and its toxicity is low. Bismuth acetate can also be used as an initiator to polymerize L-lactide in chlorobenzene and as an acylating agent for ammonia and alcohols. |
| preparation | 50g of bismuth oxide was dissolved in a mixture of glacial acetic acid and 20ml of acetic anhydride, the reaction was carried out by heating under reflux at 150 ° C. Until the bismuth oxide was completely dissolved. The obtained reaction liquid was cooled to precipitate a solid, and the precipitated solid was obtained by filtration. The precipitated solid was dissolved in 100ml of glacial acetic acid at ° C., cooled and crystallized, and then filtered to obtain crystals. The obtained crystals were washed with ethyl acetate, and the washed product was vacuum dried, 81.5G of bismuth acetate were obtained in a yield of 99.31%. |
