Abstract: The invention relates to a method for producing vicinal diols or polyols from an organic reaction mixture containing formic acid esters of vicinal diols or polyols. The reaction mixture is treated with water without adding bases and thermally treated afterwards, whereby the formic acid esters are hydrolyzed, the aqueous formic acid is separated and the vicinal diols or polyols remain.
