General description

Butyraldehyde (n-Butyraldehyde), an aliphatic aldehyde, can be synthesized by dehydrogenation of butanol in the presence of zinc catalyst. It is an important precursor for preparing polyvinylbutyral.[1] The mechanism of pyrolysis of butyraldehyde in the gas-phase has been described.[2] The kinetic study of the condensation reaction between butyraldehyde and poly(vinyl alcohol) indicates retardation effect.[3]

Application

Butyraldehyde (n-Butyraldehyde) may be used in the preparation of 2-ethylhexanal (2EH) via hydrogenation in the presence of tetraamine palladium(II) chloride supported on the potassium ion-exchanged zeolite X (Pd/KXW) and on the potassium ion-added zeolite X (Pd/KXU).[4]
