1 024 mBar

Any other information on results incl. tables

Table 1. Duplicate definitive determinations of boiling temperature for WS-23 at a barometric pressure of 1024 mbar.

  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.
