| Benzoylacetone Usage And Synthesis |
| Chemical Properties | Benzoylacetone is a yellowish crystalline flakes or white crystalline solid and has balsamic odor type of medium strength. Benzoyl acetone is widely used in cosmetic industry, as a flavour and fragrance agent.Benzoylacetone is formed together with acetophenon and benzoic acid when benzoylacetic acid is boiled with water. It is also a product of the action of sodium ethylate on a mixture of acetone and ethyl benzoate. | | Uses | Benzoylacetone has been used as a 1,3-dicarbonyl compound model for studying keto-enol equilibria in aqueous acid and micellar solutions. Additionally, it has been studied using gas-phase electron diffraction and quantum chemistry. It is used as pharmaceutical intermediates. | | Synthesis Reference(s) | Chemistry Letters, 9, p. 257, 1980Journal of the American Chemical Society, 75, p. 626, 1953 DOI: 10.1021/ja01099a031Tetrahedron Letters, 37, p. 3885, 1996 DOI: 10.1016/0040-4039(96)00689-2 | | Safety Profile | Moderately toxic by ingestion.When heated to decomposition it emits acrid smoke andirritating vapors. | | Purification Methods | Crystallise benzoylacetone from Et2O or MeOH and dry it under vacuum at 40o.
