Applicant's summary and conclusion
- Conclusions:
- During the subsequent heating phase, the test item showed a distinct endothermic signal, which can be assigned to the melting point. Due to the fact, that the onset temperatures differ by more than 0.5 K from their mean value of -16.9 °C, the test item has a melting range under atmospheric pressure of 18 to -16 °C.
- Executive summary:
The test item1-Ethyl-3-methylimidazoliumbis(trifluoromethylsulfonyl)imide has a melting range of -18 to -16 °C at atmospheric pressure (999 to 1008 hPa) as determined by means of DSC according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
