| Boiling Point (C) | ||
| Observed | Pressure corrected* | |
| Run 1 | 252.5 | 252.0 |
| Run 2 | 252.5 | 252.0 |
* Pressure correction according to the following equation:
Cb = Tb + 0.00009 (101 -Pb)(273 +Tb)
where
Cb is the corrected boiling point (°C)
Pb is the ambient barometric pressure (mbar)
Tb is the observed boiling point (°C)
Applicant's summary and conclusion
- Conclusions:
- The boiling temperature of WS-23 was determined using the Siwoloboff method. The boiling point of WS-23 was determined to be 252°C.
- Executive summary:
The boiling temperature of WS-23 was determined to be 252°C.
