<p>Dehydrating alcohol comprises dehydrating an organic compound (E) containing one or more hydroxyl groups per molecule, in presence of a liquid medium and an acid catalyst (K) at 180-280[deg] C, where the liquid medium contains an ionic liquid, whose anionic part is e.g. fatty alcohol sulfate-building block; and is obtained by reacting corresponding ionic liquid with same cationic building block, but having a halide, as an anionic building block, with a compound from e.g. an acid semi ester of a fatty alcohol sulfate, and removing the obtained hydrogen halide gas form the reaction mixture. Dehydration of alcohols comprises dehydrating an organic compound (E) containing one or more hydroxyl groups per molecule, in the presence of a liquid medium and an acid catalyst (K) at 180-280[deg] C, where the liquid medium: contains an ionic liquid, whose anionic part is a fatty alcohol sulfate-, fatty alcohol ether sulfate- or sulfonate-building block; and is obtained by reacting corresponding ionic liquid with same cationic building block, but having a halide, as an anionic building block, with a compound (I) from (i) an acid semi ester of a fatty alcohol sulfate or a fatty alcohol ether sulfate and (ii) sulfonic acid, and removing the obtained hydrogen halide gas form the reaction mixture.</p> |
