Abstract
A process for the preparation of perhaloacyl peroxides from perhaloacyl halides which is performed in the presence of a hydrofluoroether as the solvent.
Claims10
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.
4 more elements
A mixture comprising a perhaloacyl peroxide and a hydrofluoroether, wherein the mixture contains from 0.05 to 0.35 g of perhaloacyl peroxide per cm3 of 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.
