What does the "E" stand for in 'E-85' Gasoline?
Sorry, but the сorrect answer is:
E-85 (also called flex fuel) is a grade of gasoline that contains 85% Ethanol. Ethanol is a a colorless volatile flammable liquid C2H5OH that is the intoxicating agent in liquors and is also used as a solvent and in fuel —called also ethyl alcohol, grain alcohol.
Since 2005, U.S. ethanol production capacity has more than tripled and now stands at more than 13 billion gallons per year.
It is produced by yeast fermentation of carbohydrates or, synthetically, by hydration of ethylene. Most of E-85 for cars --an alternative fuel-- is derived from corn, grains or agricultural waste or it is chemically extracted from ethylene.
