Diethyl Ether Is Produced From Ethanol
Diethyl ether is produced from ethanol according to the following equation.
Diethyl ether is produced from ethanol. Most diethyl ether is produced as a byproduct of the vapor phase hydration of ethylene to make ethanol. Diethyl ether is produced from ethanol according to the following equation. 2 moles of ethanol 1 mol of ether. There are two ways to make diethyl ether ch3ch2och2ch3 from ethanol ch3ch2oh.
The first and most straightforward is to mix ethanol with a strong acid typically sulfuric acid h2so4. The molecular weight of diethyl ether is 74 1. 2ch3ch2oh l รข ch3ch2och2ch3 l h2o l 100. The acid dissociates in the aqueous like environment produci.
G of ethanol reacts to produce 66 0 g of ether. Diethyl ether ethanol c6h16o2 cid 21585056 structure chemical names physical and chemical properties classification patents literature biological. Diethyl ether can be prepared both in laboratories and on an industrial scale by the process called acid ether synthesis. This strong acid dissociates in the aqueous environment producing h 3 o hydronium ions.
2ch3 ch2 oh ch3 ch2 och2 ch3 h2o. 11 what is the theoretical yield. This process uses solid supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises. 100g of ethanol 100 46 moles 50 46 moles of ether 50 46 74 80 4347 g.
46 0 g of ethanol x 1 mol 46 0 g 1 mole of ethanol. Diethyl ether is produced from ethanol according to the following equation. Calculate the percent yield if 68 6 g of ethanol reacts to produce 16 1 g of ether. Ethanol is mixed with a strong acid like sulfuric acid h 2 so 4.
100g of ethanol dry ethanol is best is placed in a 1 2 liter distilling flask and with good cooling 180g of. This is also called ethyl ether or ether and must not be confused with petroleum ether if for example you see a formula calling for ether then it refers to diethyl ether if it does not specify petroleum ether then do not use petroleum ether. Vapor phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95. This question was set up to make the math easy since the molecular weight of ethanol is about 46 0 g mol.
