	Ethyl Formate
		Ethyl formate is a colorless liquid with a pleasant, fruity odor; it is highly flammable and poses a dangerous fire and explosion risk.
		Before a worker is placed in a job with a potential for exposure to ethyl formate, 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 formate is not subject to EPA emergency planning requirements under the Superfund Amendments and Reauthorization Act (SARA) (Title III) in 42 USC 11022.

	Case Study: Pyrolysis of Ethyl Formate
		In this study, you will generate the transition state for ethyl formate's breakdown into ethylene and formic acid.
		So, resave your structure of ethyl formate as another file, called formic acid and ethylene (or something similar!).
		Orient them so that they are fairly similar, and make ethyl formate the active molecule.

		Ethyl alcohol was first detected in the interstellar medium in 1975 by a team led by Ben Zuckerman, but proved elusive in subsequent searches.
		In a recent article, they show that in Orion the spatial distribution of ethyl alcohol is similar to that of other, large oxygen-bearing molecules such as methanol, methyl formate and dimethyl ether and is associated with a hot core called the Compact Ridge cloud.
		The detection of such large amounts of ethyl alcohol, and previous detections of even larger amounts of methanol, in hot cores suggests that grain surface chemistry may be very efficient in producing alcohols.

	Re: What are the accepted scents for isoamyl formate & ethyl methanoate
		Isoamyl formate (also known as isoamyl methanoate) naturally occurs in apples, so it has an "apply smell." It is used in perfumes to mimic the scents of plums, berries, apple cider, raspberries, oranges, and pears.
		Ethyl formate derived from cabbage is used to mimic the scents of raspberries, melons, mulberries, flberries, and currant.
		Ethyl formate derived from raspberries is used when the scents of tea, mulberries, beer, strawberries, or butter are desired.

		Hence, the alkaline hydrolysis of ethyl acetate may be monitored by following the change in the electrical conductance of the reaction mixture with time.
		Ethyl formate is hydrolyzed at different temperatures between 5°C and 15°C. A reaction temperature below the room temperature is obtained and maintained by careful addition of ice or cold water to the water bath.
