Butyraldehyde, also known as butanal, is an organic compound that is the aldehyde analog of butane as well as an isomer of butanone. It is a colorless flammable liquid with an acrid smell. It is miscible with most organic solvents.
It can be produced by catalytic dehydrogenation of 1-butanol, catalytic hydrogenation of crotonaldehyde, or via the hydroformylation of propylene.
Upon exposure to air, it is oxidized to form butyric acid.
