Propylene glycol can be dehydrated to propionaldehyde which can in turn be reductively aminated to propylamine.

Propionaldehyde can be converted to n-propyl amine in two steps.

Step-1--Conversion of propionaldehyde to oxime

Propionaldehyde is treated with hydroxyl amine in weakly acidic medium to form imine product known as propionaldoxime.

CH₃CH₂CHO+NH₂OH->CH₃CH₂CH=N-OH+H₂O

Step-2:-Reduction of imine to form amine

In this step,propionaldoxime is reduced by proper reducing agent like Na in ethanol to form n-propyl amine.

CH₃CH₂CH=NO-Na-C₂H5OH-> CH₃CH₂CH₂NH₂

Explanation :- actually, when Propionaldehyde is treated with hydroxyl amine in weakly acidic medium to form imine product known as propionaldoxime.reaction is given by 
CH₃CH₂CHO + NH₂OH ----> CH₃CH₂CH=N-OH + H₂O
Now propionaldoxime is reduced by proper reducing agent like Na in ethanol to form n-propyl amine. reaction follow as below 
CH₃CH₂CH=NO-Na-C₂H5OH ----> CH₃CH₂CH₂NH₂
