On the other side, 2-ethylhexanol is industrially produced through three consecutive reaction processes such as, propylene hydroformylation to n-butyraldehyde, n-butyraldehyde self-condensation, and typical aldol condensation reaction, which can be catalyzed by an acid, a base, or an acid-base bifunctional catalyst, to give 2-ethyl-2-hexenal, and a hydrogenation, catalyzed by the supported Cu or Ni catalysts, of this last compound to give 2-ethylhexanol [21].
Through an aldol condensation, furfural and acetone are converted into furfuralacetone, in which subsequent hydrogenation forms 4-(2-tetrahydrofuryl)-2-butanol (THFA) [21].
