Beschreibung

Ethyl methyl ether (methoxyethane, IUPAC) is a colorless liquid that is soluble in water. Specific gravity is 0.70, which is lighter than water. It is highly flammable, with a flammable range of 2%–10.1% in air. Boiling point is 51°F (10°C), flash point is ?35°F (?37°C), and ignition temperature is 374°F (190°C). Vapor density is 2.07, which is heavier than air. In addition to flammability, ethyl methyl ether is an anesthetic and can form explosive peroxides as it ages. The four-digit UN identification number is 1039. The NFPA 704 designation is health 1, flammability 4, and reactivity 1. The primary use is in medicine as an anesthetic.

Chemische Eigenschaften

Colorless liquid. Soluble in water; miscible with alcohol and ether.

Verwenden

Medicine (anesthetic).

Definition

ChEBI: An ether that is the methyl ether derivative of ethanol.

Allgemeine Beschreibung

A clear colorless gas with a medicine-like odor. Flash point -35°F. Boiling point 52°F. Less dense than water. Vapors are heavier than air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.

Air & Water Reaktionen

Highly flammable. Soluble in water. 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)].

Reaktivität anzeigen

Ethers, such as ETHYL METHYL 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.

Hazard

Highly flammable, dangerous fire and explosion risk.

Health Hazard

Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases.

Brandgefahr

EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. CAUTION: Hydrogen (UN1049), Deuterium (UN1957), Hydrogen, refrigerated liquid (UN1966) and Methane (UN1971) are lighter than air and will rise. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.

Sicherheitsprofil

Has anesthetic properties. A very dangerous fire and moderate explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials (e.g., air, O2). To fight fire, use alcohol foam, CO2, dry chemical. See also ETHERS.

mögliche Exposition

Used as a medicine and anesthetic.

Versand/Shipping

UN1039 Methyl ethyl ether or Ethyl methyl ether, Hazard Class: 2.1; Labels: 2.1-Flammable gas.

läuterung methode

Dry the ether with CaSO4, pass it through an alumina column (to remove peroxides), then fractionally distil it. [Beilstein 1 H 314, 1 I 158, 1 II 311, 1 III 1288, 1 IV 1314.]

Inkompatibilitäten

May form explosive mixture with air. Incompatible, dangerous reaction with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.). Keep away from alkaline materials, strong acids (may be explosive), strong bases. May form explosive peroxides on standing.

Waste disposal

Dissolve 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.
