Ethyl ether

Monograph Number: 3840

Title: Ethyl Ether

CAS Registry Number: 60-29-7

CAS Name: 1,1¢-Oxybisethane

Additional Names:ethoxyethane; ether; diethyl ether; ethyl oxide; diethyl oxide; sulfuric ether; anesthetic ether

Molecular Formula: C4H10O

Molecular Weight: 74.12.

Percent Composition: C 64.82%, H 13.60%, O 21.59%

Line Formula: C2H5OC2H5

Literature References: Produced on a large scale by dehydration of ethanol or by hydration of ethylene, both processes being carried out in thepresence of sulfuric acid. Review of mfg processes: Himmler in Ullmann's Encyklopädie der Technischen Chemie, vol. 5 (1954) pp 777-782; D. E. Keeley in Kirk-Othmer Encyclopedia of Chemical Technology vol. 9 (Wiley-Interscience, New York, 3rd ed., 1980) pp 381-393.
Properties: Mobile, very volatile, highly flammable liq. Explosive! Vapor heavier than air. Characteristic, sweetish, pungent odor,more agreeable than chloroform. Burning taste. Tends to form explosive peroxides under the influence of air and light, esp when evaporation to dryness is attempted. Peroxides may be removed from ether by shaking with 5% aq ferrous sulfate soln. Addition of naphthols, polyphenols, aromatic amines, and aminophenols has been proposed for the stabilization of ethyl ether. d40 0.7364; d410 0.7249;d420 0.7134; d430 0.7019. Vapor density 2.55 (air = 1.0). mp -116.3° (stable crystals); mp -123.3° (metastable crystals). bp760 34.6°; bp400 17.9°; bp200 +2.2°; bp100 -11.5°; bp10 -48.1°; bp1.0 -74.3°. Satd vapor press. at 0°: 184.9 mm; at 10°: 290.8 mm; at 20°: 439.8 mm; at 50°: 1276 mm; at 70°: 2304 mm. Critical temp 192.7°; crit press. 35.6 atm. Flash pt, closed cup: -49°F (-45°C).Air-ether mixtures containing more than 1.85 volume-% of ether vapor, are explosive hazards.

Autoignition temp 180-190°. nD15 1.35555. Dielectric constant at 26.9° and 85.8 kilocycles = 4.197; good insulator. When shaken under absolutely dry conditions ether can generate enough static electricity to start a fire. Surface tension at 20°: 17.06 dynes/cm. Viscosity at 20°: 0.2448 cp. Heat...
