Preperation of hydrogen peroxide

Hydrogen peroxide is conveniently prepared by slowly adding 10 grams of barium peroxide to 50ml of ice cold, 20 percent by weight sulphuric acid. The addition is carried out in small portions with good stirring. Additionally, pieces of ice are added to the reaction mixture. During the addition, barium sulphate will precipitate. After the additon is completed, barium carbonate is added to remove the excess of sulphuric acid. Therafter, the mixture is filtered to recover the aqueous  solution of hydrogen peroxide.

Other names: Perhydrol, oxidanyl, perhydroxic acid, dioxidane

Preparation of high concentration hydrogen peroxide

Concentrated hydrogen peroxide may explode!!! A 500-ml. distilling flask is provided with a standard male ground joint, onto which is placed a female glass cap, equipped with a distillation capillary. The side tube of the capillary is connected with ground joints to a spiral condenser, which empties into a receiver of about 200-ml. capacity. After the introduction of 180 ml. of Perhydrol (stored in bottles coated with paraffin wax), the flask is placed on a water bath (45 to 50°C) and the material is distilled over a period of about 3.5 hours at a pressure of 16 to 22 mm. Thus, about 150-160 ml. of water and some hydrogen peroxide are removed. The residue contains approximately 98% H2O2. The volume of water to be distilled may be marked off on the previously tared receiving flask. (If the temperature of the water bath rises above 52°C, the concentrated H2O2 turns yellow and should be discarded.) The concentrated product may be removed from the flask without any danger of decomposition. (If a female ground joint were to be used at the neck of the flask, the decomposition on the rough surface would be appreciable.).

By another method 80-90% hydrogen peroxide starting material can also be obtained by mixing 30% hydrogen peroxide solution with twice its amount of p-cymene, followed by distillation of the mixture at 50°C, using an aspirator vacuum. Most of the water and p-cymene is thus removed. After mechanical separation of the remaining p-cymene-H2O2 mixture, further processing is carried out as described above.

    I’m not sure, but what would be the outcome of conc. H2SO4 + BaO2?
    Would it make H2SO5, or would it decompose the H2O2 formed? Or maybe make “High-Test” Peroxide?

      Actually, thats an interesting question. I think the low solubility product of the formed barium sulphate will limit the formation of Caro’s Acid in this case. An interesting experiment to try out!!
