Applicant's summary and conclusion
- Executive summary:
The vapour pressure of stabilized EMIM BF4 was determined following EU A.4 using the effusion method (weight loss).
Vaour pressure was examinde at 7 different temperatures. 4 temperatures could be evaluated as thes showed relevant and reproducible weight loss. For these temperatures, 1/T was plotted against log (P)
Experiment T Mean P Stand.Dev.P RSD P No. K Pa Pa % 4 348.2 1.16E-03 4.61E-04 39.9 5 363.2 5.77E-03 7.59E-04 13.1 6 378.2 1.35E-02 1.71E-03 12.7 7 393.2 6.22E-02 3.08E-04 0.5 The graph 1/T vs. log (P) shows a straight line with a correlation of -0.9936
For the test item stabilized EMIM BF4 the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 2.20E-06
Vapour pressure at 25 °C: 4.30E-06
