Benzyl ether Usage And Synthesis
| 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. |
| Chemical Properties | Dibenzyl ether has a slightly earthy, mushroom-like odor with a rosy undertone. |
| Uses | Benzyl ether is used as an effective GFP friendly tissue clearing medium for mouse brains. It is also used in a study to develop a detailed protocol for performing 3D imaging of solvent-cleared organs and its application to various microscopy techniques. It is also employed as a plasticizer for nitrocellulose and synthetic rubber, a solvent in perfumery, and a flavoring agent in chewing gums and baked goods. It can also be used as a plasticizer for nitrocellulose and a solvent in spices. |
| Application | Benzyl ether is an aromatic ether that is commonly employed as a protecting agent and benzylating agent. It is a plasticizer for nitrocellulose and a solvent in perfumery. |
| Preparation | As a by-product in the preparation of benzyl alcohol by hydrolysis of benzyl chloride; by using a concentrated causticinstead of carbonate, yields can be improved to 50% or higher. |
| Definition | ChEBI: Dibenzyl ether is a benzyl ether in which the oxygen atom is connected to two benzyl groups. It has a role as a metabolite. |
| General Description | Colorless liquid with a mild odor. |
| Air & Water Reactions | Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Insoluble in water. |
| Reactivity Profile | Benzyl ether 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. |
| 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 | Benzyl ether is combustible. |
| 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.] |
