ABSTRACT:
An improved process for the production of .alpha.,.omega.-dialdehydes by reaction of linear .alpha.,.omega.-diolefins having isolated double bonds with carbon monoxide and hydrogen at elevated temperature and at superatmospheric pressure in the presence of a cobalt carbonyl complex in which the improvement consists in supplying the cobalt to the reaction as cobalt carbonyl hydride dissolved in the .alpha.,.omega.-diolefin to be used or in an inert organic solvent and carrying out the reaction at a temperature of from 70.degree. to 130.degree.C.
