First, reduce propanone with the help of lithium aluminum hydride (LiAlH_{4}) to get propan-2-ol and then by dehydration remove water molecule to get propene.

  1. Reduce propanone to propan-2-ol: Use LiAlH4 to reduce propanone to propan-2-ol. 
  2. Dehydrate propan-2-ol to propene: Heat propan-2-ol with an excess of concentrated sulfuric acid or phosphoric(V) acid at around 170°C to dehydrate it and produce propene.
