132-64-9 Usage

General Description

Colorless white crystalline solid.

Fire Hazard

Flash point data for Dibenzofuran are not available. Dibenzofuran is probably combustible.

Purification Methods

Dissolve dibenzofuran in diethyl ether, then shake it with two portions of aqueous NaOH (2M), wash it with water, separate and dry (MgSO4) it. After evaporating the ether, dibenzofuran is crystallised from aqueous 80% EtOH and then dried under vacuum. [Cass et al. J Chem Soc 1406 1958.] High purity material is obtained by zone refining. [Beilstein 17 V 234.]

Air & Water Reactions

Insoluble in water.

Definition

ChEBI: A mancude organic heterotricyclic parent that consists of a furan ring flanked by two benzene rings ortho-fused across the 2,3- and 4,5-positions.

Chemical Properties

white to light yellow crystal powde

Reactivity Profile

Dibenzofuran is sensitive to prolonged exposure to light .
