Results and discussion
- Preliminary study:
- The percentage hydrolysis of test item was calculated as 2.1, 8.4 and 1.1% at pH 4.0, 7.0 and pH 9.0
solutions after 5 days (Table 2). The chromatograms all showed the same peak pattern as the
representative LC/MS/MS chromatograms given in Figure 2 to 4. - Test performance:
- At preliminary test (Tier I), the percentage hydrolysis of the Lithium bis(fluorosulfonyl)imide were
2.1, 8.4 and 1.1% at pH 4.0 7.0 and 9.0, respectively, indicating that little degradation was observed
between 0 and 5 days at each buffer solution in the preliminary test.
Based on these results, Lithium bis(fluorosulfonyl)imide was considered hydrolytically stable
(t0.525˚C >1year) in acidic / alkaline / neutral conditions. - Transformation products:

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
