Abstract: Water is separated by distillation from organic multiple component mixtures containing at least one component partly miscible with water. The component miscible with water is distilled azeotropically with the water contained in the mixture, the distillate is separated into water and a zeotrope forming agent and the latter is recycled to the distilling column. In the recycling process, one part of the azeotrope forming agent is conducted to the top of the column and the other part is fed into the column at the feed mixture inlet or at a location thereunder.
