FIELD: chemistry.

SUBSTANCE: present invention relates to versions of a method of dehydrating at least one oxygen-containing compound selected from saturated alcohols having from 1 to 25 carbon atoms, unsaturated alcohols having 2 to 20 carbon atoms, diols having 2 to 20 carbon atoms, in the presence of at least one dehydration catalyst selected from cerium (CeO₂), aluminium oxide (γ-Al₂O₃), aluminium silicate, aluminosilicates (SiO₂-Al₂O₃), alumina, zeolites; at least one basic agent selected from ammonia (NH₃) or from inorganic or organic compounds containing nitrogen, capable of forming ammonia (NH₃) during said dehydration method; and, optionally, silicon dioxide (SiO₂).

EFFECT: technical result is the development of a method for dehydration of oxygen-containing compounds, which prolongs the service life of the catalyst used in it and, as a result, its productivity, reduces formation of by-products which can cause catalyst poisoning, and increases output during dehydration.
