ABSTRACT:
In a process for separating trioxane from an aqueous mixture consisting essentially of trioxane, water and formaldehyde, water is extracted from the mixture by pervaporation and the water-depleted mixture (retentate) is separated by rectification into trioxane and an azeotropic mixture of trioxane, water and formaldehyde.
