Zusammenfassung:1. A process for the refining of heterocyclic compounds with nitrogen in the molecule from mixtures containing water, characterized in that the mixtures containing water are compounded with an aliphatic or cycloaliphatic solvent and a water soluble salt or mixture of salts and heated to a temperature in the range of 35 to 100 degrees C while being intensively mixed after which the phases are separated, the organic phase is worked up by distillation and the aqueous brine is extracted with an aliphatic or cycloaliphatic solvent and this extract is worked up by distillation.
