Any other information on results incl. tables

The vapour pressure was measured in the temperature range of 70 °C to 100 °C. The following values were measured:

Temperature (°C)       Vapour pressure (hPa)

70                            7.1 X 10E-5

75                            1.6 X 10E-4

80                             4.0 X 10E-4

85                             5.3 X 10E-4

90                             4.4 X 10E-4

95                             1.9 X 10E-4

100                           8.9 X 10E-5

The measured vapour pressures showed an unusual behaviour ( may be caused by the presence of a stable solvate). Above 85 °C the vapour pressure decreased with increasing temperatures. Because of the unusual behaviour discribed above the values for 20, 25 and 50 °C were estimated according to the Antoine equation. Based on the measured vapour pressure at 85 °C, the following upper limit vapour pressure values for the test item were calculated: < 1.0E-4 Pa at 20°C and 25°C and < 0.01 Pa at 50°C.

Applicant's summary and conclusion

Conclusions:
In a Guideline study according to OECD 104, the following upper limit vapour pressure values for the test item were calculated: < 1.0E-4 Pa at 20°C and 25°C and < 0.01 Pa at 50°C.
Executive summary:

The vapour pressure of the test item was determined according to OECD 104. The measured vapour pressures showed an unusual behaviour. Above 85 °C the vapour pressure decreased with increasing temperatures. Because of the unusual behaviour discribed above the values for 20, 25 and 50 °C were estimated according to the Antoine equation. Based on the measured vapour pressure at 85 °C, the following upper limit vapour pressure values for the test item were calculated: < 1.0E-4 Pa at 20°C and 25°C and < 0.01 Pa at 50°C.
