1-Propanol structure (the white balls are the hydrogen atoms, the red ball is the oxygen atom, and the black (or gray) balls are the carbon atoms.

1-Propanol (also known as propan-1-ol, propyl alcohol, or just propanol) is an alcohol. The chemical formula is CH3CH2CH2OH or C3H8O. It is an isomer of isopropanol. It appears as a flammable, colourless liquid.

Uses

1-Propanol is harder to make than isopropanol, which can be made cheaply from a direct hydration reaction of propylene as predicted by Markovnikov's rule. Making 1-propanol from propene needs a more complicated process, so it is more expensive. Cheaper alcohols like ethanol and isopropanol are more common for househould use.

In the chemical industry, its differences from isopropanol can matter more, and it is sometimes used as a solvent. It is also an ingredient in other chemicals like n-propyl bromide.

Preparation

1-Propanol is made from hydrogenation of propanal, itself usually made from hydroformylation of ethylene:[1]

C2H4 + CO + H2 → C2H5COH
C2H5COH + H2 → C3H7OH
