1. Ethylene carbonyl synthesis: Ethylene synthesis of propanal by carbonyl, and then reduced to n-propanol.
2. Propylene oxide hydrogenation.
3. Recovery from isopropanol by-product: When propylene is directly hydrated to isopropanol, the by-product is n-propanol from which n-propanol is recovered.
4 Separated from the oxidation of lower alkanes.
5. Allyl alcohol hydrogenation.
6 Propionaldehyde Hydrogenation Propyl alcohol is obtained by the catalytic hydrogenation of propionaldehyde.
