	Ethyl chloride - Wikipedia, the free encyclopedia
		Ethyl chloride is a chemical compound once widely used in producing tetraethyl lead, a gasoline additive.
		Ethyl chloride is produced by reacting ethylene and hydrogen chloride over an aluminium chloride catalyst at temperatures ranging from 130-250°C. Under these conditions, ethyl chloride is produced according to the chemical equation.
		At various times in the past, ethyl chloride has also been produced from ethanol and hydrochloric acid, or from ethane and chlorine, but these routes are no longer economical.

	Ethyl - Wikipedia, the free encyclopedia
		Ethyl is a two-carbon substituent in organic chemistry.
		"Ethyl" was also the common designation in North America for high-performance commercial gasoline containing Lead in the mid 20th century.
		The term comes from the name of the company, Ethyl Corporation, which manufactured the antiknock organometallic agent tetraethyl lead added to the gasoline.

	Ethyl Acrylate (Site not responding. Last check: 2007-10-07)
		Ethyl acrylate is a colorless liquid with a sharp, acrid odor.
		Ethyl acrylate is fetotoxic at near-toxic maternal doses and has caused skeletal abnormalities in the offspring of pregnant rats fed ethyl acrylate during gestation [NLM 1991].
		Before a worker is placed in a job with a potential for exposure to ethyl acrylate, a licensed health care professional should evaluate and document the worker's baseline health status with thorough medical, environmental, and occupational histories, a physical examination, and physiologic and laboratory tests appropriate for the anticipated occupational risks.

	Ethyl Acetate
		Ethyl acetate is a clear, colorless, flammable liquid with a pleasant, fruity odor.
		The oral LD(50) for acute exposure to ethyl acetate is 4,935 mg/kg for rabbits and 5,620 mg/kg for rats; and the 8-hour rat inhalation LC(50) is 1600 ppm [Sax and Lewis 1989].
		Before a worker is placed in a job with a potential for exposure to ethyl acetate, a licensed health care professional should evaluate and document the worker's baseline health status with thorough medical, environmental, and occupational histories, a physical examination, and physiologic and laboratory tests appropriate for the anticipated occupational risks.

	NAFTA & Environmental Laws: The Case of Canada and Ethyl Corp.
		The Ethyl suit raises a host of issues that should be of concern to policymakers particularly since the U.S. is negotiating the expansion of NAFTA as well as a new multilateral investment agreement (MAI) that would apply NAFTA-like standards worldwide.
		If Ethyl wins its case, a precedent will be set whereby the legal right of corporations to be compensated when public health regulations affect a company’s bottom line is given the same weight as the public’s right not to be harmed by industrial toxins.
		Ethyl also claims that the legislative debate itself constituted an expropriation of its assets because public criticism of MMT damaged the company’s reputation.

	HHMI Lab Safety: LCSS: ETHYL ACETATE
		Ethyl acetate is a flammable liquid (NFPA rating = 3), and its vapor can travel a considerable distance to an ignition source and "flash back." Ethyl acetate vapor forms explosive mixtures with air at concentrations of 2 to 11.5% (by volume).
		Ethyl acetate should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C, supplemented by the additional precautions for dealing with highly flammable substances (Chapter 5.F).
		In particular, ethyl acetate should be used only in areas free of ignition sources, and quantities greater than 1 liter should be stored in tightly sealed metal containers in areas separate from oxidizers.

		Ethyl alcohol taken in via ingestion passes from the mouth down the esophagus and into the stomach and on into the small intestine.
		Ethyl alcohol crosses with water into the blood stream, therefore the process of distribution of alcohol is rapid.
		Ethyl alcohol decreases the ability of the body to concentrate urine, thus promotes water loss rather than allowing the water to be absorbed back into the body.

	The Fuel of the Future
		Ethyl alcohol has long been used as an automotive fuel in two ways: First, it replaces gasoline outright in a somewhat modified internal combustion engine; and secondly, it is an effective "octane booster" when mixed with gasoline in blends of 10 to 30 percent and requires no engine modification.
		Opponents have seen ethyl alcohol fuel as a scheme for robbing taxpayers to enrich farmers, as turning food for the poor into fuel for the rich, as compounding soil erosion problems, and as a marginally useful enhancement or replacement fuel for a transportation system that is poorly designed in the first place.
		It was a blend of high-proof ethyl alcohol with 20 to 50 percent turpentine to color the flame and a few drops of camphor oil to mask the turpentine smell.

		Millions of pounds of toxic industrial solvents could be replaced by environmentally friendly solvents made with ethyl lactate, thanks to a new cost-cutting manufacturing process developed by researchers from Argonne's Energy Systems Division.
		Although ethyl lactate has been around for years, the cost of producing it has been too high to allow it to compete economically with lower-priced chemical solvents.
		Ethyl lactate normally sells for $1.60 to $2.00 per pound, compared with about 90 cents to $1.70 per pound for conventional chemical solvents.
