Direct synthesis of ethanol over a Cu–Zn catalyst in the liquid phase
Abstract
Cu–Zn and Cu–Al catalysts generated by reduction of Cu(acac)2(acac = acetylacetonato) with ZnEt2 or AlEt3, are shown to produce oxygenated compounds from syngas in the liquid phase under pressure; high selectivities for ethanol are observed, especially with the Cu–Zn system (45.7 mol%) in the early stages of the reaction.
