Abstract
Alkylbenzaldehyde is continuously produced in high yield from alkylbenzene by formylation with carbon monoxide in the presence of HF--BF.sub.3, where the alkylbenzene, HF--BF.sub.3 and carbon monoxide under a carbon monoxide partial pressure of at least 5 kg/cm.sup.2 absolute are introduced into the reactor to continuously carry out complexing of the alkylbenzene with HF--BF.sub.3 and formylation with the carbon monoxide successively in one and same reactor.
