Dibenzoylmethane

1,3-디페닐-1,3-프로판디온 C화학적 특성, 용도, 생산

화학적 성질

Dibenzoylmethane (DB), a minor constituent of the root extract of licorice, belongs to the flavonoid family. It is a colorless rhombus flake crystal or yellowish-white powder. soluble in chlorohydrin and chloroform, soluble in sodium hydroxide solution, insoluble in sodium carbonate solution, and very slightly soluble in water. It is used as a colorimetric reagent for the determination of uranium.

출처

Dibenzoylmethane(DBM) is a 1,3-diketone derivative of acetylacetone that has both methyl groups replaced with phenyl groups.Although smaller in size and lacking hydroxyl and methoxy groups，DBM resembles the turmeric spice curcumin (CUR),a diferuloylmethane. Both molecules are metal-chelating agents，contain a B-diketone flanked by two aryl groups,and exhibit anti-proliferative and anticarcinogenic activity. In addition to sharing structural similarity with DBM,CUR,which is also a naturally occurring compound is found in the plant Curcuma longa and has numerous medicinal uses.
DBM and its many naturally occurring derivatives are minor constituentsof licorice. DBM has been isolated from licorice root extracts and otherspecies of Glycyrrhiza.

용도

Dibenzoylmethane is a new kind of PVC heat stabilizer, it has better transparency, nontoxic and odorless. In case of combined use with Calcium/Zinc, Barium/Zin and other heat stabilizer, it can greatly improve the initial color, transparency, long term stability of PVC, and also can improve the precipitation and “zinc burning” problem during the process. It has very good synergy with zinc soaps, and can protect the PVC color. This material can absorb UV at 290nm, which has the effect as light stabilizer and act as long term stabilizer for PVC products.

정의

ChEBI: Dibenzoylmethane is a beta-diketone that is acetylacetone (acac) in which both methyl groups have been replaced by phenyl groups.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 anticancer effects. It has a role as an antineoplastic agent, a metabolite and an antimutagen. It is a beta-diketone and an aromatic ketone.

제조 방법

dibenzoylmethane is prepared by condensation of ethyl benzoate with acetophenone.

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.]
