Abstract
There is disclosed a method of producing 1,9-nonanedial and/or 9-hydroxy-7-nonen-1-al which comprises reacting 2,7-octadien-1-ol with a mixture of hydrogen and carbon monoxide in an organic solvent in the presence of a rhodium catalyst and 30-300 equivalents of a monodentate tertiary organic phosphorus compound in per gram atom of rhodium at a hydrogen partial pressure of 0.5-20 kg/cm.sup.2 (absolute) and a carbon monoxide partial pressure of 0.1-5.0 kg/cm.sup.2 (absolute).
