Abstract: An organic compound having at least one C-C double bond is epoxidized by means of hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent, wherein a product mixture comprising alpha-hydroperoxyalcohols is reduced using at least one reducing agent. The process advantageously comprises at least the following steps: (i) reacting an organic compound having at least one C-C double bond with hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent to give a product mixture P1 comprising alpha-hydroperoxyalcohols; (ii) separating an epoxide formed in the reaction in step (i) and the unreacted organic compound having at least one C-C double bond from P1 or P1' to give a product mixture P2 or P2', where P2 comprises the alpha-hydroperoxyalcohols formed as by-product in the reaction in step (i) and P2' is largely free of alpha-hydroperoxyalcohols; (iii) treating P1 and/or P2 with at least one reducing agent so that the alpha-hydroperoxyalcohols are converted into corresponding glycols to give a product mixture P1' or P3.
