Description
Peroxide, bis[2,2,2-trifluoro-1,1-bis(trifluoromethyl)ethyl], also known as perfluoropropyl peroxide, is a colorless, non-flammable, and stable peroxide with a high degree of fluorination. It is a chemical compound with the formula C8F18O2, characterized by its high stability and reactivity.
Uses
Used in Polymerization Industry:
Peroxide, bis[2,2,2-trifluoro-1,1-bis(trifluoromethyl)ethyl] is used as a radical initiator for the polymerization of perfluorinated monomers, such as tetrafluoroethylene and vinylidene fluoride. It facilitates the formation of high-performance polymers with exceptional properties.
Used in Fluoroelastomer Production:
In the fluoroelastomer industry, perfluoropropyl peroxide is utilized as a curing agent. It readily decomposes to produce free radicals that initiate the cross-linking of polymer chains, resulting in the creation of durable and heat-resistant elastomers.
Used in Aerospace, Automotive, and Electronics Industries:
Due to its high stability and reactivity, perfluoropropyl peroxide has applications in the production of specialized materials for the aerospace, automotive, and electronics industries. It contributes to the development of advanced materials with unique properties, such as high-temperature resistance and chemical inertness.
It is crucial to handle perfluoropropyl peroxide with care, as it can be a strong oxidizing agent and react with a wide range of materials. Proper safety measures should be taken during its use to prevent any potential hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 26842-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,4 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26842-85:
(7*2)+(6*6)+(5*8)+(4*4)+(3*2)+(2*8)+(1*5)=133
133 % 10 = 3
So 26842-85-3 is a valid CAS Registry Number.

Perfluoro Alkyl Hypofluorites and Peroxides Revisited
Nissen, Jan H.,Drews, Thomas,Schr?der, Benjamin,Beckers, Helmut,Steinhauer, Simon,Riedel, Sebastian
, p. 14721 - 14727 (2019)
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.

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.
