| Hazard Information | Back Directory | [General Description]
Colorless liquid with a mild odor. | [Reactivity Profile]
DIBENZYL ETHER(103-50-4) can act as a base to form salts with strong acids and addition complexes with Lewis acids. May react violently with strong oxidizing agents. Burns readily but relatively inert in other reactions, which typically involve the breaking of the carbon-oxygen bond. | [Air & Water Reactions]
Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Insoluble in water. | [Hazard]
Moderately toxic by ingestion. A skin irri-
tant.
| [Health Hazard]
Inhalation may cause nausea because of disagreeable odor. Contact of liquid with eyes causes mild irritation. Prolonged exposure of skin to liquid causes reddening and irritation. Ingestion produces nausea. | [Fire Hazard]
This chemical is combustible. | [Chemical Properties]
Dibenzyl ether has a slightly earthy, mushroom-like odor with a rosy undertone. | [Chemical Properties]
Dibenzyl ether is a clear, almost colorless liquid. It is miscible with alcohols and ethers, but insoluble in water. Dibenzyl ether is used as special solvent and delustering agent for textiles.
| [Uses]
Plasticizer for nitrocellulose; solvent in perfumery. | [Definition]
ChEBI: A benzyl ether in which the oxygen atom is connected to two benzyl groups. | [Preparation]
As a by-product in the preparation of benzyl alcohol by hydrolysis of benzyl chloride; by using a concentrated caustic
instead of carbonate, yields can be improved to 50% or higher. | [Synthesis]
Benzyl ether is formed when benzyl alcohol is heated with strong acids or bases. It is produced almost exclusively by the alkaline hydrolysis of benzyl chloride. Heat treatment decomposes dibenzyl ether into benzaldehyde and toluene. | [Purification Methods]
Reflux the ether over sodium, then distil it under reduced pressure. It been purified by fractional freezing. [Beilstein 6 IV 2240.] |
