Question
How is diethyl ether prepared by continuous esterification process?
✓
Answer
When an excess of ethyl alcohol is distilled with concentrated $H_2SO_4$ at $413 K (140 ^\circ C),$ diethyl ether is formed.
This reaction takes place in two steps:
Step$-I:$ Formation of ethyl hydrogen sulphate:
When excess of ethyl alcohol is heated with concentrated $H_2SO_4,$ ethyl hydrogen sulphate is obtained.
Step$-II:$ Formation of diethyl ether: Ethyl hydrogen sulphate then reacts with excess of ethyl alcohol at $413 K$ and forms diethyl ether.
