摘要：
The present invention relates to a process for obtaining trimethylolpropane-enriched product streams from the forerun fractions obtained in the distillative purification of trimethylolpropane, these fractions being catalytically hydrogenated separately or in combination in the presence of an acidic compound and worked up by distillation, and a trimethylolpropane-enriched product stream being removed. In a further aspect of the invention, separation from solids follows the hydrogenation and precedes the distillative workup.
