• W4235856803 abstract "[7722-84-1] H2O2 (MW 34.02) InChI = 1S/H2O2/c1-2/h1-2H InChIKey = MHAJPDPJQMAIIY-UHFFFAOYSA-N (nucleophilic reagent capable of effecting substitution reactions2 and epoxidation of electron-deficient alkenes;3 weak electrophile whose activity is enhanced in combination with transition metal oxides4 and Lewis acids;5 strong nonpolluting oxidant which can oxidize hydrogen halides6) Physical Data: 95% H2O2: mp −0.41 °C; bp 150.2 °C; d 1.4425 g cm−3 (at 25 °C). 90% H2O2: mp −11.5 °C; bp 141.3 °C; d 1.3867 g cm−3. 30% H2O2: mp −25.7 °C; bp 106.2 °C; d 1.108 g cm−3. Solubility: sol ethanol, methanol, 1,4-dioxane, acetonitrile, THF, acetic acid. Form Supplied in: clear colorless liquid widely available as a 30% aqueous solution and 50% aqueous solution; 70% and 90% H2O2 are not widely available. Analysis of Reagent Purity: titration with KMnO4 or cerium(IV) sulfate.7 Purification: 95% H2O2 (caution!) can be prepared from 50% solution by distilling off water in a vacuum at rt.8 Handling, Storage, and Precautions: H2O2 having a concentration of 50% or more is very hazardous and can explode violently, particularly in the presence of certain inorganic salts and easily oxidizable organic material. A safety shield should be used when handling this reagent.9 After the reaction is complete, excess H2O2 should be destroyed by treatment with MnO2 or Na2SO3 soln. Before solvent evaporation, ensure absence of peroxides. The use of acetone as solvent should be avoided.10 The reagent should be stored in aluminum drums in a cool place away from oxidizable substances." @default.
