Versuchsvorschrift

The aldol condensation of propanal or butanal is an important step in the production of oxo alcohols such as 2-ethyl hexanol. For example, as described in GB 1462328, butanal is typically condensed using an aqueous caustic catalyst at a temperature of the order of 80 to 140° C. to give 2-ethyl hexenal which is then hydrogenated to 2-ethyl hexanol.
