Any other information on results incl. tables
The vapour pressure was measured with the dynamic method in the temperature range of 62 °c to 171 °C. The measured vapour pressures at the corresponding temperatures are listed in the following table:
Temperature/°C Vapour pressure/hPa
62.0 9.9
80.1 32.2
92.9 60.9
104.2 90.0
108.0 122.3
123.9 201.4
133.4 301.9
143.4 400.9
150.9 501.4
157.3 601.5
162.0 699.9
171.0 898.7
The values for 20, 25 and 50 °C are calculated, using the Antoine constants A, Band C as shown.
T/°C p/ hPa log (p/hPa) = A + 8/(C+ T[°C])
20 2,4341E-01 A = 5,95716
25 4,2960E-01 B = -842,15
50 4,2921E+00 C= 108,16
Applicant's summary and conclusion
- Conclusions:
- The substance has a vp = 43 Pa at 25°C
