Abstract

A process for preparing vicinal diols or polyols from an organic reaction mixture containing formic esters of vicinal diols or polyols, in which water is added to the reaction mixture, without addition of bases, and the formic esters are hydrolyzed in a subsequent thermal treatment, the aqueous formic acid is removed, and vicinal diols or polyols remain behind.
