Conversion of benzene into ethene involves following steps.
Step-1:—Conversion of benzene into ethyne.
Benzene is treated with ozone to form benzene triozonide,which is heated with zinc dust to form glyoxal.
Glyoxalis reduced by LiAlH₄ to give ethylene glycol,which on dehydration by conc. H₂SO₄ gives ethyne.
Step-2:—Hydrogenation of ethyne.
Ethyne is reacted with hydrogen in presence of catalyst like Ni or Pd or Pt to form ethene.
