How is ethene prepared from ethanol ?

Question:

How is ethene prepared from ethanol ? Give the reaction involved in it.

Solution:

From ethanol: This method involves the slow oxidation of a dilute solution of ethanol (10-15 per cent) by oxygen present in air in the presence of an

enzyme acetobactor.

The acid obtained is in the form of dilute solution called vinegar.

We have also studied under ethanol that it gets oxidised to ethanoic acid in the presence of dilute solution of alkaline KMnO4 or acidified K2Cr2O7.
