Abstract: A process for treating butanediol obtained as a condensate during the manufacture of polybutylene terephthalate, wherein an alkali metal alcoholate or alkali metal hydride is added to the condensate at an elevated temperature. After purification, the butanediol obtained is re-used for the manufacture of polybutylene terephthalate.
