Procedure

The production of 2-ethylhexanol (2EH) from normal butyraldehyde (NBD) is being industrially conducted on a large scale. This process is constituted of an NBD condensation step in which two molecules of NBD undergo aldol condensation and dehydration to give 2-ethylhexenal (ethylpropylacrolein, EPA), an EPA hydrogenation step in which the EPA obtained is reacted with hydrogen to obtain crude 2EH, and a 2EH purification step in which the crude 2EH is purified to a desired purity to obtain a 2EH product. The purification of crude 2EH is conducted mainly by distillation.
