Preparation of ether by dehydration of alcohol is one the simple method often carried out in an industrial production ether.
As such we are going to discuss ether production from simple or symmetrical alcohol
DEHYDRATION OF ALCOHOL
Is simple mean the broken down of alcohol by removing it hydroxyl, leaving alkyl group as a separate component of the product
When the ethanol is heated with high concentration of acid for example tetraxosulphate (VI) acid , it breake into the following
Now, the general formula of ether is ROR
R is the functional group of the ether that will substituted for alkyl group of the alcohol, while the OH group of the alcohol is loss to form water molecule.
Two ethanol are heated in the present of concentrated tetraxosuplate (VI) or (V) acid, it yield ethyl ethoxy methane
This is shown below
The of the reaction is
CH3CH2-O-CH2CH3 + 2H2O
(Ethoxy ether ethane ) water
Ethoxy ether is the ether form by dehydration excess concentration of Alcohol in the present of concentrated acid.
