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.
