Results
The equation of the linear regression curve to determine the PT was: log PT,20 = -1751 x 1/T + 9.84 (r = 0.9999, n = 14). The results for the vapour pressure of the test item at 20°C and 25°C are:
| Temperature (°C) | log PT | PT (Pa) | PT (mm Hg) |
| 20 | 3.86 | 7.3E+3 | 5.4E+1 |
| 25 | 3.97 | 9.4E+3 | 7.0E+1 |
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item was determined to be 7.3E+3 Pa (or 5.4E+1 mmHg) at 20°C (293K) and 9.4E+3 Pa (or 7.0E+1 mmHg) at 25°C (298K).
