Zusammenfassung:	Process for the preparation of alpha, beta unsaturated aldehydes by oxidation of alcohols in the presence of a liquid phase wherein the liquid phase contains 0.1 to less than 25weight-% water and wherein the liquid phase contains at least 25 weight-% of alcohol(s) of general formula (II) and alpha, beta unsaturated aldehyde(s) of general formula (I) and wherein the oxidant is oxygen and/or hydrogen peroxide. L'invention concerne un procédé de préparation d'aldéhydes alpha, bêta insaturés par oxydation d'alcools en présence d'une phase liquide, la phase liquide contenant 0,1 à moins de 25 % en poids d'eau et au moins 25 % en poids d'alcool(s) de formule générale (II) et d'aldéhyde(s) alpha, bêta insaturé(s) de formule générale (I) et l'oxydant étant de l'oxygène et/ou du peroxyde d'hydrogène.
