ethene from ethanol

Ethanol

Production Most ethanol is usually produced in one of two ways using either petroleum or biomass Petroleum derived ethanol happens in large chemical plants through a petrochemical process Raw materials are separated from petroleum through fractional distillation Ethane () one of the separated raw materials goes through cracking to become ethene () also referred to as ethylene

What is the percentage yield when 7g of ethene

As 1 mole of ethene react to give 1 mole of ethanol So 0 25 mole of ethene react to give 0 25 mole of ethanol Now we have to calculate the mass of ethanol The theoretical yield of ethanol = 11 5 g The experimental yield of ethanol = 6 g Now we have to calculate the percent yield of ethanol Therefore the percent yield of ethanol is 52 17%

Ethanol manufacture

Ethanol is manufactured by reacting ethene with steam The reaction is reversible and the formation of the ethanol is exothermic Only 5% of the ethene is converted into ethanol at each pass through the reactor By removing the ethanol from the equilibrium mixture and recycling the ethene it is possible to achieve an overall 95%

Learn the Pros and Cons of Ethanol and Its Production

Ethanol is simply another name for alcohol--the liquid made from the fermentation of sugars by yeasts Ethanol is also called ethyl alcohol or grain alcohol and is abbreviated as EtOH In the context of alternative fuels the term refers to an alcohol-based fuel that is blended with gasoline to produce a fuel with a higher octane rating and fewer harmful emissions than unblended gasoline
