Molecule Structure Image



Butyraldehyde is the aldehyde derivative of butane. Butyraldehyde is produced almost exclusively by the hydroformylation of propylene. Butyraldehyde can be produced by the catalytic dehydrogenation of n-butanol. Butyraldehyde is used as an intermediate in the manufacturing plasticizers, alcohols, solvents and polymers (such as 2-Ethylhexanol, n-butanol, trimethylolpropane, n-butyric acid, polyvinyl butyral, methyl amyl ketone). It is also used as an intermediate to make pharmaceuticals, agrochemicals, antioxidants, rubber accelerators, textile auxiliaries, perfumery and flavors.
