PROCESS FOR THE PURIFICATION OF DIETHOXYPMETHANE FROM A MIXTURE WITH ETHANOL AND WATER Abstract A process for purifying diethoxymethane from a mixture containing ethanol and, optionally, water. The process involves the addition of an amount of water, DEM, or an appropriate mixture of any two or three of water, DEM and ethanol that is effective in moving the mixture into the two liquid phase region on an equilibrium tie-line which crosses the critical distillation boundary without the need for additional azeotrope-forming agents such as cyclohexane.
