The present invention refers to an aqueous hydrogen peroxide solution comprising: i) less than 50 wppm alkali metals, alkaline earth metals or combinations thereof in total, irrespective whether the alkali or alkaline earth metals are present in cationic or complex form; ii) less than 50 wppm of amines having a pkB of less than 4.5 or the corresponding protonated compounds in total; andiii) at least 100 wppm anions or compounds that can dissociate to form anions in total, whereby the wppm are based on the weight of hydrogen peroxide and the concentration of hydrogen peroxide is more than 50 % by weight based on the total weight of the hydrogen peroxide solution, a process for preparation of said hydrogen peroxide solution and the use of said solution in a process for epoxidation of olefins.

La présente invention concerne une solution de peroxyde d'hydrogène aqueuse qui comprend: (i) moins de 50 wppm de métaux alcalins, de métaux de terre rare alcalin ou d'une combinaison de ceux-ci au total, que cet alcalin ou ces métaux de terre rare alcalins soient présents sous forme cationique ou complexe, (ii) moins de 50 wppm d'amines possédant un pk<SB>B</SB> inférieur à 4,5 ou les composés de protonation correspondant au total et, (iii) au moins 100 wppm d'anions ou de composés qui peuvent se dissocier pour former des anions au total, ces wppm étant basés sur le poids du peroxyde d'hydrogène et la concentration de peroxyde d'hydrogène étant supérieure à 50 % en poids du poids total de la solution de peroxyde d'hydrogène. Cette invention concerne aussi un processus de préparation de cette solution de peroxyde d'hydrogène et l'utilisation de cette solution dans un processus d'époxidation d'oléfines
