  • Publication number: 20130261319
    Abstract: The present invention relates to a method for preparing 1,3,5-trioxane using a distillation tower including a reactor, a distillation section, and an extraction section. Particularly, the present invention relates to a method for preparing 1,3,5-trioxane, in which the water phase separated from the stream discharged through the extraction unit of the reaction distillation tower is used in the process of extracting 1,3,5-trioxane.

  • Publication number: 20130261318
    Abstract: The present invention relates to a method for preparing 1,3,5-trioxane using a reaction distillation tower including a reactor and integrally formed distillation and extraction sections. Particularly, the present invention relates to a method for preparing 1,3,5-trioxane characterized in that the amount of formaldehyde discharged to the outside of the system is reduced, to thereby increase the yield of 1,3,5-trioxane by recirculating a portion of the water phase, which is discharged through the top of the reaction extraction tower, to the extraction section, and thus to the upper portion of the extractor supply stream which supplies extractant to the extraction section.
