Usage

General Description

Peroxide, bis[2,2,2-trifluoro-1,1-bis(trifluoromethyl)ethyl], also known as perfluoropropyl peroxide, is a chemical compound with the formula C8F18O2. It is a colorless, non-flammable, and stable peroxide with a high degree of fluorination. Peroxide, bis[2,2,2-trifluoro-1,1-bis(trifluoromethyl)ethyl] is primarily used as a radical initiator in the polymerization of perfluorinated monomers, such as tetrafluoroethylene and vinylidene fluoride. It is also used as a curing agent for fluoroelastomers, as it readily decomposes to produce free radicals that initiate the cross-linking of polymer chains. Due to its high stability and reactivity, perfluoropropyl peroxide has applications in the production of specialized materials for the aerospace, automotive, and electronics industries. However, it is important to handle this chemical with care, as it can be a strong oxidizing agent and react with a wide range of materials.

Perfluoro Alkyl Hypofluorites and Peroxides Revisited

A more convenient synthesis of the perfluoro alkyl hypofluorite (F3C)3COF as well as the hitherto unknown (C2F5)(F3C)2COF compound is reported. Both hypofluorites can be prepared by use of the corresponding tertiary alcohols RFOH and elemental fluorine in the presence of CsF. An appropriate access to these highly reactive hypofluorites is crucial. The hypofluorites are then transferred into their corresponding perfluoro bisalkyl peroxides RFOORF [RF=(F3C)3C, (C2F5)(F3C)2C] by treatment with partially fluorinated silver wool. NMR, gas-phase infrared, and solid-state Raman spectra of the perfluoro bisalkyl peroxides are presented and their chemical properties are discussed.

Organic compounds bearing a difluoroaminooxy group

A preparative method for the synthesis of C-and N-difluoroaminooxy compounds was elaborated. The method involves the reaction of N,N-difluoro-O-fluorosulfonyl hydroxylamine with the corresponding alkoxides and N-oximide salts. It was shown that N-difluoroaminooxy compounds can add to olefins at the double bond.

PROCESS FOR THE PREPARATION OF FLUORINATED PEROXIDES

The present invention relates to the preparation of perfluorinated or partially fluorinated peroxides which avoids the use of carbonyl fluoride (COF2).
