Zusammenfassung:Process for obtaining ditrimethylolpropane and trimethylolpropane-enriched product streams from the high-boiling fractions and residues which are obtained in the distillative purification of trimethylolpropane includes three stage distillation characterized in that second and third stages are configured as thin film evaporators with a column attachment with the second stage facilitating trimethylopropane recovery and the third stage facilitating ditrimethylolpropane recovery.
