Di-n-butyl ether Usage And Synthesis
Chemical Propertiescolourless liquid with ether-like odour
Chemical PropertiesButyl Ether is a flammable, colorless liquid with a mild, ethereal odor.
UsesSolvent for hydrocarbons, fatty materials; extracting agent used especially for separating met- als, solvent purification, organic synthesis (reaction medium).
General DescriptionA clear colorless liquid with an ethereal odor. Flash point below 141°F. Less dense than water and insoluble in water. Vapors heavier than air. Irritates the eyes, nose, throat, and respiratory tract.
Air & Water ReactionsHighly flammable. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164]. A mixture of liquid air and diethyl ether exploded spontaneously [MCA Case History 616 1960]. Insoluble in water.
Reactivity ProfileEthers, such as BUTYL ETHER 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.
HazardToxic on prolonged inhalation. Flammable, moderate fire risk. May form explosive peroxides, especially in anhydrous form.
Health HazardInhalation causes irritation of nose and throat. Liquid irritates eyes and may irritate skin on prolonged contact. Ingestion causes irritation of mouth and stomach.
Fire HazardBehavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.
Safety ProfileMildly toxic by inhalation, ingestion, and skin contact. Human systemic effects by inhalation: conjunctiva irritation and unspecified nasal effects. An experimental skin and human eye irritant. See also ETHERS. Dangerous fire hazard when exposed to heat, flame, oroxidizers. Incompatible with NCL and oxidizing materials. To fight fire, use alcohol foam, dry chemical. When heated to decomposition it emits acrid smoke and fumes.
Potential ExposureIt is used as a solvent for hydrocarbons, fatty materials; extracting agent in used metals separation; solvent purification, making other chemicals. Incompatibilities: May form explosive mixture with air. May accumulate static electrical charges, and may cause ignition of its vapors. Incompatible with strong acids; oxidizers. Contact with air or light may form unstable and explosive peroxides, especially anhydrous form.
First aidthis chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit

Purification MethodsPeroxides (detected by the liberation of iodine from weakly acid HCl solutions of 2% KI) can be removed by shaking 1L of ether with 5-10mL of a solution comprising of 6.0g of ferrous sulfate and 6mL conc H2SO4 and 110mL of water, with aqueous Na2SO3, or with acidified NaI, water, then aqueous Na2S2O3. After washing with dilute NaOH, KOH, or Na2CO3, then water, the ether is dried with CaCl2 and distilled. It can be further dried by distillation from CaH2 or Na (after drying with P2O5), and stored in the dark with Na or NaH. The ether can also be purified by treating with CS2 and NaOH, expelling the excess sulfide by heating. The ether is then washed with water, dried with NaOH and distilled [Kusama & Koike J Chem Soc Jpn, Pure Chem Sect 72 229 1951]. Other purification procedures include passage through an activated alumina column to remove peroxides, or through a column of silica gel, and distillation after adding about 3% (v/v) of a 1M solution of MeMgI in n-butyl ether. [Beilstein 1 IV 1520.]
Waste DisposalDissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
