Overview

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.
