The invention relates to a process for the extractive removal of phenols, alcohols, amines, phoshines, hydroxylamines, hydrazines, oximes, imines, water, carboxylic acids, amino acids, hydroxamic acids, sulfinic acids, sulfonic acids, peroxycarboxylic acids, phosphonous acids, phosphinous acids, phosphonic acids, phosphinic acids or phosphoric acids from aprotic solvents by means of ionic liquids of the formula [K]+[A], where n, [K]and Aare defined as in the description.

Method for extracting impurities using ionic liquids

Method for the production of 1,3,5-trifluoro-2,4,6-trichlorobenzene from fluorobenzene comprising steps A) and B): A) chlorination of fluorobenzene derivatives of formula (II), in which X=fluorine of H, Z=nitro, bromo or chloro and n=0 or 1-4 and B) fluorination of the distillation residue and separation by distillation of the 1,3,5-trifluoro-2,4,6-trichlorobenzene thus produced.
