How do you Convert Propanone to Propene

Answer: The following procedures can be used to convert propanone to propene.

  1. Propanone is reduced to 2-propanol
  2. Then 2-propanol is dehydrated to propene.
  • In the reduction of ketones to secondary alcohols, the following reagents can be utilised as reducing agents.
  • Lithium aluminium hydride (LiAlH4)
  • Sodium borohydride (NaBH4)
  • Na / Ethanol
  • H2 / Pt
  • The powerful oxidising agent is LiAlH4. When propanone interacts with LiAlH4, the result is 2-propanol, which is a secondary alcohol.
  • A secondary alcohol is 2-propanol. When secondary alcohol is cooked in a dehydrator, the result is an alkene compound.
  • The reacting mixture should be heated with the following dehydrators. Temperature, on the other hand, is dependent on the type of dehydrator utilised.
  • Concentrated H2SO4 and 1700 °C
  • Al2O3and 3500 °C
  • P2O5and heat
  • H3PO4and heat
  • Propene is formed when 2-propanol is heated with concentrated H2SO4acid and a water molecule is removed.
