Abstract

The preparation of polyol compounds by (a) condensing glycerine in the presence of lithium compounds; (b) continuously distilling off the water produced by the reaction; (c) optionally subjecting the oligoglycerine mixture obtained to a transesterification reaction with fatty-acid glyceride esters. Such polyol compounds are suitable for use as starting materials in the production of polymers.
