ether

 [e´ther]
1. an organic compound containing an oxygen atom bonded to two carbon atoms.
2. diethyl or ethyl ether: a colorless, transparent, mobile, very volatile, highly flammable liquid with a characteristic odor; it was the first inhalational anesthetic used for surgical anesthesia, but is now rarely used in the United States or Canada because of its flammability.

e·ther

(ē'thĕr),
1. Any organic compound in which two carbon atoms are independently linked to a common oxygen atom, thus containing the group -C-O-C-.
See also: epoxy.
2. Loosely used to refer to diethyl ether or an anesthetic ether, although a large number of ethers have anesthetic properties. For individual ethers, see the specific name.

ether

(ē′thər)
n.
1. Any of a class of organic compounds in which two hydrocarbon groups are linked by an oxygen atom.
2. A volatile, highly flammable liquid, C4H10O, derived from distilling ethyl alcohol with sulfuric acid, used as a reagent and solvent, and formerly used as an anesthetic. Also called diethyl ether, ethyl ether.
3. The regions of space beyond the earth's atmosphere; the heavens.
4. The element believed in ancient and medieval civilizations to fill all space above the sphere of the moon and to compose the stars and planets.
5. Physics An all-pervading, infinitely elastic, massless medium formerly postulated as the medium of propagation of electromagnetic waves.

ether

A volatile and highly inflammable liquid once widely used as a safe and effective drug for the induction and continuance of general anaesthesia. Induction is slow and unpleasant and deep anaesthesia is needed for muscle relaxation. Postoperative nausea is common. Because of these disadvantages and the danger of explosion, ether is now seldom used. The drug is, however, on the WHO official list.

Cleavage of the diphenyl ether bond. Most recent research has focused on the hydroxylated PBDE metabolites, but few articles have reported diphenyl ether bond cleavage.
Previous studies have reported the cleavage of the diphenyl ether bond of PBDEs in the gas phase (Raff and Hites 2006) and of a PBDE-like thyropropionic acid in solution (Matsuura et al.
The self-assembly behavior of [TiO.sub.2] on the surface of polymer with the terminal functional groups (e.g.,--COOH,--[SO.sub.2]0H, and sulfone group) and ether bond may be illustrated by two different adsorption schemes as it is shown in Fig.
The asymmetrical stretching vibration of -C[F.sub.3] groups produces absorption at ~1300 [cm.sup.-1], and the stretching absorption of the ether bond in ODA moieties appears at ~1245 [cm.sup.-1].
has been granted a patent for a starch-based coating composition comprised of a naturally derived resin and a resin composition obtained by reacting a starch and/or a starch that has been esterified, etherified, oxidized, acid treated or dextrinated or modified by comprising one or more groups selected from the group consisting of aliphatic saturated hydrocarbon groups, aliphatic unsaturated hydrocarbon groups, and aromatic hydrocarbon groups, which are bonded by ester bonds and/or ether bonds to the starch or to a decomposition product of a starch that has been processed by a low molecularization treatment with an enzyme, acid or oxidizing agent, with a compound containing an isocyanate group obtained by reacting a polyisocyanate compound and a polyhydric alcohol.
