Applicant's summary and conclusion
- Conclusions:
- Calculation of the vapor pressure of 2-COUMARANONE 100 at 25 °C by interpolation based upon the simplified Clausius-Clapeyron equation resulted in a vapor pressure of 1.3 x 10-1 Pa at 25 °C.
- Executive summary:
The vapor pressure of the test item 2-COUMARANONE 100 has been determined using the gas saturation method. The vapor pressure of 2-COUMARANONE 100 was measured at test temperatures of 10 °C, 20 °C and 30 °C and was determined to be
2.7 x 10-2Pa at 10 °C
6.7 x 10-2Pa at 20 °C
2.4 x 10-1Pa at 30 °C
The vapor pressure of 2-COUMARANONE 100 at 25 °C was interpolated from the vapor pressure curve and was calculated to be
1.3x 10-1Pa at 25 °C
