What are the products when ethyl alcohol is heated?

Answer 1

Ethanol when heated with presence of AlCl3 as a catalytic amount undergoes dehydation as result a loss of water giving ethene gas as a major product.

This is a simple way of making gaseous alkenes like ethene. If ethanol vapour is passed over heated aluminum oxide powder, the ethanol is essentially cracked to give ethene and water vapour.

To make a few test tubes of ethene, you can use this apparatus:

Answer 2

It explodes. Spontaneous combustion.
