Anisole Chemical Properties,Usage,Production

Product Features

Anisole, also known as anise ether, methoxybenzene methyl phenyl ether, is a colorless liquid with an odor of anise, sweet, naturally present in the tarragon oil, insoluble in water, soluble in alcohol, ether, acetone, soluble in benzene. It irritates the eyes and mucous membranes. It is obtained originally from distilled methyl salicylate or methoxybenzoate, is now mainly produced through the reaction of methylating agent of dimethyl sulfate with phenol in alkaline aqueous solution. Anisole is prone to start Electrophilic substitution reaction in aromatic nucleus, and condensed with formaldehyde to produce viscous oil or resin material, reacts with phosphorus trichloride to produce chlorine anisole and a small amount of o-chloro product, reacts with thionyl chloride to produce 2,4,6-trichloroanisole. In addition, anisole is heated to react with hydrobromic or hydroiodic, carbon-oxygen bond cleaves, phenol and halogenated methane is produced, which is an important method for determining methoxy group of benzene ring.

General Description

A clear straw-colored liquid with an aromatic odor. Insoluble in water and the same density as water. Vapors heavier than air. Flash point 125°F. Boiling point 307°F. Moderately toxic by ingestion. A skin irritant. Used to make perfumes, flavorings and as a solvent.

Air & Water Reactions

Flammable. Ethers tend to form unstable peroxides when exposed to oxygen. Ethyl, isobutyl, ethyl tert-butyl, and ethyl tert-pentyl ether are particularly hazardous in this respect. Ether peroxides can sometimes be observed as clear crystals deposited on containers or along the surface of the liquid. Insoluble in water

Reactivity Profile

Ethers, such as Anisole can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Safety Profile

Moderately toxic by ingestion and inhalation. A skin irritant. A flammable liquid. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid fumes.

Potential Exposure

Anisole is used as a solvent; a flavoring, vermicide, making perfumes; and in organic synthesis.

Purification Methods

Shake anisole with half its volume of 2M NaOH, and the emulsion is allowed to separate. Repeat three times, then wash twice with water, dry over CaCl2, filter, dry over sodium wire and finally distil it from fresh sodium under N2 using a Dean-Stark trap (samples in the trap being rejected until free from turbidity) [Caldin et al. J Chem Soc, Faraday Trans 1 72 1856 1976]. Alternatively dry it with CaSO4 or CaCl2, or by refluxing with sodium or BaO with crystalline FeSO4 or by passage through an alumina column. Traces of phenols are removed by prior shaking with 2M NaOH, followed by washing with water. It has been be purified by zone refining. [Beilstein 6 IV 548.]
