| titleOfInvention | Method for separating trioxane from a mixture containing trioxane, formaldehyde and water |
| abstract | The invention relates to a method for separating trioxane from a mixture containing formaldehyde, trioxane and water. According to said method: the mixture (1) is distilled in a first distillation stage (7) at a pressure of between 0.1 and 2 bar to obtain a stream (8) containing formaldehyde and a stream (9) containing predominantly trioxane, in addition to water and formaldehyde; the stream (9) is mixed with a recycling stream (19) containing predominantly trioxane, in addition to water and formaldehyde to form a stream (10) containing predominantly trioxane, in addition to water and formaldehyde; the stream (10) is then distilled in a second distillation stage (14) at a pressure of between 0.2 and 10 bar, optionally after the separation of low-boilers from the stream (9) or (10) in an additional distillation stage (11). The pressure in the second distillation stage (14) is at least 0.1 bar higher than the pressure in the first distillation stage (7). Said distillation produces a stream (15) consisting of trioxane and a stream (16) containing predominantly trioxane, in addition to water and formaldehyde. The stream (16) is then distilled in a third distillation stage (17) at a pressure of between 0.1 and 4 bar, to obtain a stream (18) containing predominantly water, in addition to formaldehyde and the recycling stream (19) containing predominantly trioxane, in addition to water and formaldehyde. The resultant stream (18) is optionally distilled in a fourth distillation stage (20), to obtain a stream (21) containing predominantly water and a stream (22) containing predominantly formaldehyde. |
