Abstract: Olefinically unsaturated compounds containing 4 to 36 carbon atoms and having boiling points above 40.degree.C are converted into the corresponding vicinal diols by reaction with formic acid and hydrogen peroxide at elevated temperature while intimately mixing and by subsequent saponification of the diol formates initially formed. The formic acid is used in amounts of 2 to 6 moles per mole of double bond and hydrogen peroxide is used in a concentration of 35 to 98 percent by weight. The reaction is carried out a temperature between 40 to 80.degree.C. The desired diols can usually be obtained in reaction times of less than seven hours and in yields of approximately 90%.

Abstract: Hydrogen peroxide is extracted from the working solution of the alkyl anthraquinone process by solvents which are lighter than water and which produce the dispersed phase in the extraction step. The extraction is carried out in unfilled towers which at the bottom are fitted with known elements for dispersing organic liquids, e.g. perforated plates.

Abstract: Styrene, its derivatives substituted in the aromatic nucleus or at the vinyl group by a methyl group or its derivatives substituted at the vinyl group by a hydroxy-methyl group are reacted at a temperature between 40 and 80.degree.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 applied in a concentration between 20 and 100 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. The corresponding diols and triols are formed directly from the olefins applied within reasonable reaction times in high yields.
