Any other information on results incl. tables
The vapour pressure was measured with the dynamic method in the temperature range of 65 °C to 165 °C. The measured vapour pressures at the corresponding temperatures are listed in Table 1.

Temperature / °C | Vapour pressure / hPa |
65.0 | 20.0 |
83.3 | 50.0 |
99.8 | 100.0 |

Figure 1 on page 8 gives the vapour pressure (logarithmic scale) as a function of the inverse temperature (1/T, T in Kelvin). Only for better readability the temperature is reported in a centigrade scale.
From the measured data the parameters A, B and C of the Antoine equation can be derived by regression.
The evaluated Antoine parameters are listed Table 2.
Table 2: Antoine parameters
A | 8.21896 |
B | -2327.28 |
C | 273.15 |
The vapour pressure values for 20, 25 and 50 °C (see Table 2) were extrapolated, using these Antoine constants A, B and C.
