摘要

Process for the purification of arcana from its azeotropic mixture with ethanol using as an ionic liquid solvent. The aim of the present invention is the obtaining of a high purity alkane which is found in the azeotropic mixtures of ethanol with alkanes; these mixtures are present in the petrochemical industry in large quantities. In this invention, ionic liquids are proposed as solvents in a liquid-liquid extraction process. The selected solvent is the ionic liquid 1,3-dimethylimidazolium methyl sulfate. The proposed purification process consists of a continuous liquid-liquid extraction stage; followed by a solvent recovery step for reuse in the extraction column.
