ABSTRACT OF THE DISCLOSURE A compound selected from 3-chloro-2-methyl-propene-1, straight-chain or branched monoolefins, which are either unsub- stituted or substituted by 1 to 2 hydroxyl groups and contain 4 to 7 carbon atoms and have a terminal or internal double bond, straight-chain or branched monoolefins, which are unsubstituted or substituted by 1 to 2 hydroxyl groups and contain 8 to 12 carbon atoms and an internal double bond and straight-chain or branched diolefins containing 4 to 10 carbon atoms are reacted at a temperature between 30 and 80°C with less than 2 moles of formic acid and less than 2 moles of hydrogen peroxide per mole of double bond to be hydroxylated. Formic acid is used in a concentration between 20 and 50 percent by weight and hydrogen peroxide in a concentration of less than 50 percent by weight. The concentration of the hydrogen peroxide in the aqueous phase of the reaction mixture is kept below 15 percent by weight during the entire reaction. From the monoolefins the corresponding diols and polyols are obtained directly in high yields within acceptable reaction times.
