| titleOfInvention | Process for the separation of formaldehyde and trioxane |
| abstract | A process for the separation of a gaseous reaction mixture in the production of trioxane is described, in which a) the gaseous mixture leaving the reactor is washed with an organic solvent, the boiling point of which is higher than 135 ° C., in countercurrent, in which the trioxane is washed predominantly dissolves and the formaldehyde remains predominantly in the gas phase, which is returned to the reactor, b) the trioxane together with the remaining formaldehyde is driven off from the solvent by distillation via a column, the overhead product in the temperature range from 62 to 100 ° C is partially condensed, c) the condensate formed is partly passed to the column as reflux, partly drawn off as product, and d) the uncondensed fraction is returned to washing step a). |
