1. A process for the preparation of a perhaloacyl peroxide said process comprising:
contacting an aqueous phase comprising an inorganic peroxide with a mixture of a perhaloacyl halide and a hydrofluoroether,
allowing the inorganic peroxide to react with the perhaloacyl halide to obtain a perhaloacyl peroxide, and
separating the aqueous phase from a mixture comprising the perhaloacyl peroxide and the hydrofluoroether,
wherein the hydrofluoroether is selected from the hydrofluoroethers of formula (IA):
R—O—R′  (IA)
with the proviso that at least one of R or R′is a —CmF2m−1 group or a —CnF2n+1−hHh group wherein m≥3; n≥3, h<2n+1, and at least one of R or R′ is a —CnF2n+1−hHh group wherein 1≤n≤3 and h=2n+1.
