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. The mechanism of pyrolysis of butyraldehyde in the gas-phase has been described. The kinetic study of the condensation reaction between butyraldehyde and poly(vinyl alcohol) indicates retardation effect.
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).
