Abstract
The present invention relates to a process for the dehydration of at least one oxygenated compound, preferably selected from saturated alcohols, unsaturated alcohols, diols, ethers, in the presence of at least one dehydration catalyst selected from cerium oxide (CeO2), aluminium oxide (γ-Al2O3), aluminium silicate, silica-aluminas (SiO2—Al2O3), aluminas, zeolites, sulfonated resins, ion-exchange resins, metal oxides (for example, lanthanum oxide, zirconium oxide, tungsten oxide, thallium oxide, magnesium oxide, zinc oxide); of at least one basic agent selected from ammonia (NH3), or from inorganic or organic compounds containing nitrogen capable of developing ammonia (NH3) during said dehydration process; and, optionally, of silica (SiO2), or of at least one catalyst for the dissociation of ammonia (NH3) selected from catalysts comprising silica (SiO2), preferably of silica (SiO2).
