    Abstract: The invention relates to an integrated method for producing trioxane from formaldehyde. According to said method, a flow A1 containing water and formaldehyde as well as a recirculation flow B2 substantially composed of water and formaldehyde are delivered to a trioxane synthesis reactor in which the formaldehyde is reacted to trioxane such that a product flow A2 containing trioxane, water, and formaldehyde is obtained. Flow A2 and a recirculation flow D1 containing trioxane, water, and formaldehyde are fed to a first distillation column and are distilled at a pressure ranging from 0.1 to 2.5 bar such that a trioxane-enriched flow B1 and flow B2, which is essentially composed of water and formaldehyde, are obtained. Flow B1 is delivered to a second distillation column and is distilled at a pressure ranging from 0.2 to 17.5 bar such that a product flow substantially comprising trioxane and a flow C1 containing trioxane, water, and formaldehyde are obtained. Flow C1 is fed to a third distillation column and is distilled at a pressure ranging from 1 to 10 bar such that the recirculation flow D1 containing trioxane, water, and formaldehyde as well as a flow D2 that is substantially composed of water are obtained.
