Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012-05-30 to 2012-12-06
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study has been performed according to OECD guideline 104 and EU method A.4 in a GLP certified testing facility.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- yes
- Remarks:
- (lnstead of screw-caps, crimp-caps were used to close the Knudsen cells. The deviation was assessed as uncritical as crimp-caps close the cells more tightly.)

- Conclusions:
- The vapour pressure of 400112 was determined following EU A.4 and OECD guideline 104 using the effusion method (weight loss).
Based on the regression equation the vapour pressures at 20°C and at 25 °C were calculated for the test item 400112:
Vapour pressure at 20°C: 5.67 * 10E-06 Pa
Vapour pressure at 25°C: 1.07 * 10E-05 Pa - Executive summary:
The vapour pressure of 400112 was examined in nine different experiments using the effusion method (weight loss) with temperatures ranging from 30 to 150°C. The measurements at 30, 45, and 75°C showed no significant and/or no reproducible weight loss. The measurements at 60°C showed a significant weight loss, but no second temperature in the range of 30 - 75°C which could be used for evaluation. lt was considered that the weight loss at 60°C was caused by minor impurities of the test item. Therefore, experiments 1 - 4 were not included in the evaluation. At temperatures between 90 and 150°C (experiments 5 -9) a reproducible weight loss could be measured. For these temperatures, 1/T was plotted against log (P). The graph 1/T vs. log (P) shows a good correlation (r² = 0.9990). Based on the regression equation the vapour pressures at 20°C and at 25°C were calculated for the test item 400112.
Vapour pressure at 20°C: 5.67 * 10E-06 Pa
Vapour pressure at 25°C: 1.07 * 10E-05 Pa
All measured values of the five evaluated experiments show good reproducibility, giving relative standard deviations of less than 20%, and good correlation. The result of the test can be considered valid.
Reference
Experiments 1, 2 and 4 (nominal temperatures of 30, 45 and 75 °C) showed no significant weight and/or no reproducible loss. Experiment 3 (nominal temperature of 60 °C) showed a significant weight loss, but no second temperature in the range of 30 - 75 °C which could be used for evaluation. lt was considered that the weight loss at 60°C was caused by minor impurities of the test item. Therefore, experiments 1-4 were not included in the evaluation. All measurement data from experiments 5-9 (at temperatures of 90, 105, 120, 135, and 150 °C) was included in the evaluation as significant and reproducible weight loss was observed.
Upon inspection of the cells after the third measurement series at 150 °C, it was observed that the test item began to change its colour to reddish. Therefore, the cells were not weighed after the third measurement series at 150 °C and the test was finished.
