RESULTS
- The vapour pressure result from the preliminary run was reported as 2.62 Pa at 20°C (293.15 K).
- The direct values of the vapour pressure at 25 °C are shown in Table 3 and Figure 2 (attached).
- The direct values of the vapour pressure at 40 °C are shown in Table 4 and Figure 3 (attached).
- The direct values of the vapour pressure at 70 °C are shown in Table 5 and Figure 4 (attached).
RESULTS
- Results from the preliminary run at 21 to 41°C are given in Table 1 (attached).The preliminary run self-terminated at 41 °C due to the mass difference exceeding the programmed 1500μg threshold.
- A graph of preliminary vapour pressure data is shown in Figure 2 (attached).
- The direct values of the vapour pressure at 25 °C are shown in Table 2 and Figure 3 (attached).
- The direct values of the vapour pressure at 40 °C are shown in Table 3 and Figure 4 (attached).
- The direct values of the vapour pressure at 70 °C are shown in Table 4 and Figure 5 (attached).
