Results and discussion

Any other information on results incl. tables

Since 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether has a molecular formula of C4H3F7O and a molecular weight of 200.07g/mol, the oxygen balance can be calculated as -68%, using the above formula. The value is within the region for potential explosivity however, there are no plososphores (confer explosive properties) or auxoploses (explosive enhancing groups) present in the structure, meaning the high oxygen balance is due to the presence of the ether group in the molecule.

Overall consideration of the properties of 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether does not suggest a risk of explosivity.

Applicant's summary and conclusion

Interpretation of results:
Division 1.6 (extremely insensitive articles which do not have a mass explosion hazard) based on GHS criteria
Conclusions:
1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether is not explosive
Executive summary:

The molecular structure of 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether does not contain any chemically instable or highly energetic groups that might lead to explosion. With a value of -68%, the oxygen balance of 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether is within the region where there is potential for explosivity. However, there are no plosophores or auxoploses present and so, the high oxygen balance is considered due to the ether group present. Therefore, it has been concluded that 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether is not explosive.
