| Abstract: | The reactions between formaldehyde and n-propyl radicals were studied at 333 and 363 K. Addition to the C=O bond was found to be several times faster than abstraction of the formyl hydrogen atom. With a TST estimate of log(A/dm3 mol–1 s–1)=7.9±0.5, 28.0±2.1 kJ mol–1 was obtained for the activation energy of the addition reaction.
