    Abstract: The invention relates to a method for distilling an aqueous polymethylol mixture, comprising a polymethylol of formula (I), where R independently = a further methylol group, or 1 to 22 C alkyl, or a 6 to 22 C aryl or aralkyl group, a tertiary amine, water and the adduct of tertiary amine and formic acid, (amine formate), characterised in that the distillation is carried out in a distillation column connected to an evaporator at the kettle, wherein the kettle temperature is maintained above the boiling point of the mono-ester of formic acid and polymethylol (polymethylol formate) formed during the distillation. The invention further relates to a composition comprising polymethylol and 1 to 10,000 ppm by weight of polymethylol formate and the use thereof.
