Question

Name a solid which can be used instead of concentrated sulphuric acid to prepare ethylene by dehydration of ethanol ?

Answer 1

Phosphorus pentoxide -P2O5
OR
Aluminium oxide. -Al2O2

Answer 2

Apart from concentrated sulfuric acid, solid substances such as phosphoric acid or Alumina can be used to prepare ethylene by dehydration of ethanol.

• In the given case, the given reactant is ethanol (alcohol) and the required product is ethylene (alkene).
• Alkenes can be obtained from ethanol through the following mechanisms:

1. Heating with concentrated sulfuric acid.
2. Heating with phosphoric acid.
3. Passing the vapors of ethanol over heated alumina at 350°C.

• Thus it is inferred that apart form concentrated sulfuric acid solid substance such as phosphoric acid or alumina can be used to prepare ethylene by dehydration of ethanol.
