    Abstract: The invention relates to a method for removing formic acid from a mixture that contains formaldehyde, trioxane, water and formic acid, by distillation. According to said method, at least one tertiary amine and/or an imine or a mixture thereof capable of deprotonation and conversion to a salt is added, prior to or during distillation, to the mixture in a catalytic amount or in an amount sufficient to form the salt with the entire amount of formic acid, and the formic acid/amine salt is removed in a liquid phase in the distillation sump.
