Observations
The mass of sample weighed was 10.42 mg. The sample was placed in a Knudsen effusion cell with an aperture size of A = 280 micrometer. Then, the cell was placed in the apparatus.
Temperature steps at 81, 85 and then 96°C were made. After the test, a clear yellow limpid liquid was observed in the cell.
Vapour pressure results
The vapour pressure of the test item was calculated by the "Knudsen software". The calculation results are summarized in the following table.
Test temperature t (°C) |
Test temperature T (K) |
1/T (K-1) | Experimental vapour pressure P (Pa) | Log P (Pa) | Knudsen effusion cell size (micrometer) |
| 81 | 354.15 | 2.82E-3 | 6.3871E-3 | -2.195 | 280 |
| 85 | 385.15 | 2.79E-3 | 8.8970E-3 | -2.051 | 280 |
| 96 | 369.15 | 2.71E-3 | 2.2782E-2 | -1.642 | 280 |
