Explanation:

What are Ethers?

Ethers are the organic compounds containing an oxygen atom bonded to two same or different alkyl or aryl groups. We can write the general formula for ethers as R-O-R, R-O-Ar or Ar-O-Ar. As we already know from the chapter of nomenclature, R represents an alkyl group and Ar represents an aryl group.

Preparation of Ethers

These days, with the advancement in technology, we can synthesise ethers in industries in a number of ways. Let us now look at some of the most common industrial methods of preparation of ethers.

Preparation of ethers

Preparation of Ethers by Dehydration of Alcohols

In the presence of protic acids (sulphuric acid), alcohols undergo dehydration to produce alkenes and ethers under different conditions. For example: in the presence of sulphuric acid, dehydration of ethanol at 443 K yields ethene. On the other hand, it yields ethoxyethane at 413 K. This is an ideal method of preparation for primary alcohols.
