Aqueous hydrogen peroxide solution, process for its preparation and use thereof

摘要

The present invention refers to an aqueous hydrogen peroxide solution having a hydrogen peroxide concentration [H2O2] expressed as % by weight of the solution and an apparent pH of from pHmin to pHmax, such that pHmin=3.45-0.0377×[H2O2], and pHmax=3.76-0.0379×[H2O2]. The present invention also relates to a process for the preparation of said hydrogen peroxide solution and the use of said solution in a process for the epoxidation of olefins.
