Dibenzoylmethane Usage And Synthesis
Chemical Propertiesyellowish-white powder
Usesantineoplastic
Usesdibenzoylmethane as a new PVC heat stabilizer, high transmittance, non-toxic and tasteless; can greatly improve the early PVC coloring, transparency, long-term stability, and processing during precipitation and "zinc burn" and so on; widely used in medical, food packaging and other non-toxic transparent PVC products. Dibenzoylmethane above can absorb 290nm ultraviolet light, while light having a stabilizing effect on PVC products can provide long-term stable performance.
DefinitionChEBI: A beta-diketone that is acetylacetone (acac) in which both methyl groups have been replaced by phenyl groups. It is a minor constituent of the root extract of licorice (Glycyrrhiza glabra) and exhibits antimutagenic and antica cer effects.
Synthesis Reference(s)Chemical and Pharmaceutical Bulletin, 29, p. 2762, 1981
Chemistry Letters, 10, p. 1087, 1981
Tetrahedron Letters, 37, p. 3885, 1996 DOI: 10.1016/0040-4039(96)00689-2
Safety ProfileModerately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating vapors
Purification MethodsDibenzoylmethane (1,3-diphenyl-1,3-propanedione) [120-46-7] M 224.3, m 8 0o. Crystallise dibenzoylmethane from pet ether or MeOH. [Beilstein 7 IV 2512.]
