Abstract

1. Process for the purification of a mixture of water/C1 -C2 -alcohol resulting from an industrial process for the manufacture of C1 -C2 -alcohol by chemical synthesis characterised in that the mixture to be treated is brought into contact, at least once, with at least one non-toxic gas in the liquid or supercritical state and the extract obtained, containing the impurities, is separated from the purified raffinate.
