Definitions
- the present invention relates to a process for preparing a mixture comprising an organic peroxide and an additional compound by transfer of said organic peroxide from a solvent into a composition comprising the additional compound.
- Organic peroxides are widely used in the chemical industry, particularly in the manufacture of plastics and rubber. They are used as initiators in the radical polymerization of monomers into thermoplastic polymers, as hardening agents for thermosetting polyester resins and as crosslinking agents for elastomers and polyethylene. In addition, organic peroxides serve as a source of free radicals in many organic syntheses.
- Organic peroxides are very unstable species. These are often explosive and flammable compounds that break down violently, making them difficult to handle. Organic peroxides can also be corrosive and toxic. In order to limit the dangers and facilitate their handling, organic peroxides are often handled in solvents.
- Esters of Peroxycarbonic Acids Journal of American Chemical Society, volume 72, page 1254 describes the synthesis of monoperoxycarbonates as well as dialkylperoxydicarbonates using a volatile organic solvent. The organic solvent is used to solve a solid handling problem, and then it is removed.
