Patent

CA 2681510

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 x [H2O2] pHmax = 3.76 - 0.0379 x [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.

La présente invention concerne une solution aqueuse de peroxyde d'hydrogène comprenant une concentration de peroxyde d'hydrogène [H2O2] exprimée en pourcentage pondéral de la solution et un pH apparent entre pHmin et pHmax, tel que pHmin = 3,45 - 0,0377 x [H2O2] pHmax = 3,76 - 0,0379 x [H2O2]. La présente invention concerne également un procédé de préparation de ladite solution de peroxyde d'hydrogène et l'utilisation de ladite solution dans un procédé d'époxydation d'oléfines.
