Dibenzoylmethane Chemical Properties,Usage,Production

  • Chemical Properties yellowish-white powder
  • Uses antineoplastic
  • Uses dibenzoylmethane 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.
  • Definition ChEBI: A beta-diketone that is acetylacetone (acac) in which both methyl groups have been replaced by phenyl groups.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.

    Chemical and Pharmaceutical Bulletin, 29, p. 2762, 1981 DOI: 10.1248/cpb.29.2762
  • Safety Profile Moderately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating vapors
  • Purification Methods Dibenzoylmethane (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.]
