    Abstract: Described is an improved process for preparing butyric aldehydes by hydroformylation of propene in the presence of cobaltcarbonyls complexed with phosphines. The process is characterized in that a reaction medium is used chosen from among N.N-dialkylamides, tetra-alkyl-ureas, aliphatic nitriles and dinitriniles, containing from two to 12 carbon atoms. The operating temperatures are between 110* and 220* C. and the operating pressures of CO+ H2 are between 20 and 400 atmospheres.
