	Ether - Wikipedia, the free encyclopedia
		Ether is the general name for a class of chemical compounds which contain an ether group — an oxygen atom connected to two (substituted) alkyl groups.
		Ethers are not to be confused with the following classes of compounds with the same general structure R-O-R. Aromatic compounds like furan where the oxygen is part of the aromatic system.
		In a primary ether this carbon is connected to only one other carbon as in diethyl ether CH An example of a secondary ether is diisopropyl ether (CH and that of a tertiary ether is di-tert-butyl ether (CH Dimethyl ether, a primary, a secondary, and a tertiary ether.

	Diethyl ether - Wikipedia, the free encyclopedia
		Diethyl ether has the formula CH It is used as a common solvent and has been used as a general anesthetic.
		Ether, mixed with ethanol, was marketed in the 19th century as a cure-all and recreational drug, during one of Western society's temperance movements.
		Ethyl ether is listed as a Table II precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances[2].

	HighBeam Encyclopedia - ether (Site not responding. Last check: 2007-10-30)
		ETHER [ether] any of a number of organic compounds whose molecules contain two hydrocarbon groups joined by single bonds to an oxygen atom.
		An ether such as ethyl ether in which both hydrocarbon groups are identical is said to be a simple, or symmetrical, ether.
		Ethers are often prepared commercially by heating an alcohol with sulfuric acid; the reaction is one of dehydration.

	Ethyl Ether
		Ethers that have been in contact with air or exposed to light for a long time may contain peroxides; ethers that contain peroxides may explode when the caps or stoppers of their containers are removed.
		Ethyl ether is also a defatting agent, and repeated exposure may cause skin drying and cracking [Genium 1988].
		Containers of ethyl ether should be protected from physical damage, direct sunlight, ignition sources, and should be stored separately from strong oxidizing agents, halogens, interhalogens, sulfur and sulfur compounds.

	Virtual Mass Spectrometry Laboratory (Site not responding. Last check: 2007-10-30)
		While ethyl ether was first created in a laboratory in 1540 by a German scientist named Valerius Cordus, it wasn't until 1841 that the anesthetic property of ether was put to work.
		In the present, ethyl ether, a volatile, colorless, and very odiferous compound, is often used as a solvent for certain oils, rubber, and other fatty compounds.
		Ether is also utilized along with other anesthetics to produce a state known as "balanced anesthesia"; this combination is used due to the slow rate at which ether causes unconsciousness in patients.

	Ethers (Site not responding. Last check: 2007-10-30)
		Low-molecular-weight ethers are flammable gases (methyl ether) or liquids (methyl ethyl ether or ethyl ether) that can produce explosive mixtures when they evaporate and mix with air.
		Ethers contain an oxygen atom bonded to two organic groups, that is, they have general formula R-O-R', where the R and R' represent organic groups.
		Ethers are prepared by the Williamson synthesis (the reaction of a metallic alkoxide with an alkyl halide) and also by the reaction of alkyl hydrogen sulfates with alcohols.

	Ethyl Ether Usage in Biomedical Research (Site not responding. Last check: 2007-10-30)
		The use of diethyl ether for anesthesia or euthanasia is discouraged in laboratory animals because of its highly flammable nature.
		Ether must always be used in an appropriate fume hood, preferably explosion-proof, which is running throughout the period of use.
		Ether should not be used near a flame source or other ignition source, such as an electric motor.

	GASMAN: Chapter 2. ETHER and ETHYL CHLORIDE
		Ethyl chloride is given until about ten stertorous breaths have been taken, then a lubricated Portex tube of suitable curvature (obtained by boiling it on a curved stylet) is passed blindly from the nose into the trachea....
		We must, therefore, conclude that, although ether anaesthesia produces unconsciousness, it is in reality a veneer, as it protects none of the brain cells against exhaustion from the trauma of surgical operations.
		In 1959 Welsh[b] reported a series of 2,920 tonsillectomies in 1934 under ethyl chloride, and a further 35,000 tonsillectomies between 1947 and 1959, also without a death, though it is not clearly stated that all of these patients were given ethyl chloride.

		Ether anesthesia of pregnant mice and rats has been reported to produce some embryotoxic and teratogenic effects; however, the authors did not consider ether anesthesia as "highly teratogenic" (Schwetz and Becker, 1970).
		Other criteria for ethyl ether exposure include a TLV of 400 ppm (1210 mg/cu.m) (ACGIH, 1984), an OSHA standard of 400 ppm, and a NIOSH recommended IDLH of 19,000 ppm in the atmosphere (Mackinson, 1980).
