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.

Abstract

Изучены реакции между формальдегидом и н-пропильными радикалами при температурах 333 и 363 К. Скорость присоединения к связи C=O несколько раз больше чем скорость отрыва атома водорода. получена энергия активации 28.0±2.1 кдж моль−1 для реакции присоединения, пользуясь lg(A/л моль−1 сек−1)=7.9±0.5 оцененным на основе теории переходных состояний.
