摘要： A noble aqueous hydrogen peroxide solution is provided to be safely controlled, stored, and shipped, and to be suitable for the epoxidation of olefin in the presence of a heterogeneous catalyst, and improve the selectivity of the catalyst to oxiranes such as propylene oxide and epichlorohydrin without impairing the hydrogen peroxide conversion rate or even while improving the conversion rate. An aqueous hydrogen peroxide solution has a hydrogen peroxide concentration[H2O2] expressed as % by weight of the solution and an apparent pH of pHmim to pHmax, wherein pHmin=3.45-0.0377x[H2O2], and pHmax=3.76-0.0379x[H2O2]. A process for preparing the aqueous hydrogen peroxide solution according to the anthraquinone loop process comprises: (a) hydrogenating a working solution comprising one or more organic solvents and one or more anthraquinone compounds; (b) oxidizing the hydrogenated working solution to form hydrogen peroxide; (c) extracting the hydrogen peroxide with an aqueous medium; (d) optionally adding a stabilizer into the extracted aqueous hydrogen peroxide solution; (e) concentrating the aqueous hydrogen peroxide solution to the target hydrogen peroxide concentration; and (f) optionally, altering the pH of the aqueous hydrogen peroxide solution.
