Process for producing alpha-acetoxypropionaldehyde.

摘要

An improvement in the process for producing alpha -acetoxypropionaldehyde by hydroformylating vinyl acetate with a mixed gas composed of hydrogen and carbon monoxide in an organic solvent in the presence of a rhodium complex and a trisubstituted phosphine and extracting alpha -acetoxypropionaldehyde from the reaction mixture with an aqueous medium is characterized in that the reaction mixture is brought into contact with a mixed gas composed of hydrogen and carbon monoxide, which meets certain specific requirements, within the temperature range of 50 DEG to 100 DEG C and thereafter subjected to extraction with an aqueous medium.
