The synthesis of higher oxygenates from CO hydrogenation, ethylene addition and methylene chloride addition to syngas has been studied over Rh/SiO{sub 2} catalyst. The insertion of linear CO into the adsorbed alkyl intermediates is the key step in the formation of higher oxygenates. Pulse transient technique incorporated with in situ infrared (IR) technique reveals that hydrogenation of acyl species is the rate limiting step for propionaldehyde formation. Increasing total pressure increases the residence time of alkyl intermediates for CO insertion.
