    摘要: A separation of mixtures of water and 2,6-dimethylmorpholine is carried out by rectifying the mixtures at a pressure at the head of the column between 6 and 150 mbars. The separated 2,6-dimethylmorpholine has a maximum water content of 500 ppm by weight and it is possible to achieve for a corresponding design of the rectification water contents of less than 1 ppm by weight of dimethylmorpholine.
