Butanal → 2-Ethylhex-2-Enal

The experiment in this example was carried out as described in Example 7 except that the first catalyst charged to the reactor was 5.02 g (6.8 mL) charge of Catalyst D; the reaction time was two hours. These results correspond to 94% butanol conversion and 57.3% conversion of theoretical butyraldehyde. Selectivities based on molar conversion of butyraldehyde: 5.6% selectivity to butylbutyrate, 54.8% selectivity to oxygenated 2-EH products and 7.0% selectivity to dehydrated 2-EH products. This example demonstrates that the Catalyst A forms only a slight amount of ester while generating butyraldehyde which undergoes aldol self-condensation over Catalyst D to form primarily 2-ethyl-2-hex-enal along with other 2-EH related compounds.
