Method for purifying polymethylols |
| abstract |
The invention is characterized in that distillation is carried out in a distillation column connected to an evaporator in a kettle and the kettle temperature is maintained above the boiling point of the monoester (polymethylol formate) of formic acid and polymethylol formed during the distillation , A polymethylol of formula (I), a tertiary amine, water and an adduct of a tertiary amine and formic acid (amine formate). The present invention also relates to a composition comprising polymethylol and from 1 to 10,000 ppm by weight of a polymethylol formate and to its use. (I) Wherein R is independently an additional methylol group or an alkyl group having from 1 to 22 carbon atoms or an aryl or aralkyl group having from 6 to 22 carbon atoms. |
