    摘要: The present disclosure relates to a process for preparing a tertiary alkyl organic peroxides comprising:
    a) in a first condensation stage, reacting a component containing at least one tertiary alcohol group with a compound containing at least one tertiary hydroperoxide function, in the presence of a catalyst and optional co-catalyst, to form a mixture comprising an organic phase comprising the tertiary alkyl organic peroxide and an aqueous phase,
    b) in a dewatering stage, separating the aqueous phase from the organic phase, and
    c) in a second condensation stage, continuing reacting the component containing at least one tertiary alcohol group with the compound containing at least one tertiary hydroperoxide group, in the presence of a catalyst and optional co-catalyst,

    wherein, in the first condensation stage, the mole ratio between the compound containing at least one tertiary hydroperoxide function and the component containing at least one tertiary alcohol group is at least 3:1, and
    wherein no dewatering takes place during the first condensation stage.
