Abstract
A process is provided for the semihydrogenation of the olefinic group in conjugated position to a carbonyl group in citral, a dienic aldehyde. The dienic aldehyde is hydrogenated with hydrogen in the presence of a palladium catalyst, a lower aliphatic alcohol, and an aqueous alkaline solution. The process is of particular application to the semihydrogenation of citral to citronellal.
