Any other information on results incl. tables
Based on the vapour pressure expected for Dehydrolinalool the test was performed at temperatures of 5.8 °C, 15.4 °C and 25.2 °C, respectively.The vapor pressure of Dehydrolinalool at 25 °C was calculated by interpolation from the vapor pressure curve.
The experimental parameters for the performance of the vapor pressure determination are summarized in Table 1 (please see full study report) . The results and the amount of nitrogen used to calculate the vapor pressure of the individual experiments are summarized inTable 2(please see full study report).
The tabulated values represent rounded results that were obtained by calculation using the exact raw data. To ensure saturation control, three different flow rates were used at each temperature.From Table 1 and Table 2 (please see attached tables)it can be clearly seen that higher flow rates did not lead to lower vapor pressures, which means that the nitrogen was saturated with test item under the conditions of the test.
The experimental results lead to the conclusion that the vapor pressure of the test item Dehydrolinalool is:
5.0 x 100 Pa at 5.8 °C
1.3 x 101 Pa at 15.4 °C
4.0 x 101 Pa at 25.2 °C
The vapor pressure at 25 °C was interpolated from the vapor pressure curve and was calculated to be 3.8 x 101 Pa. The trapping efficiency of the test item Dehydrolinalool in the first cooling trap was very good. Between 99% and 100% of the test item was trapped in the first cooling trap.The trapping efficiency results are summarized inTable 3.
Figure 1 (attached) shows the vapor pressure curve of Dehydrolinalool. The extrapolation data are given in Table 4.A typical chromatogram of a standard calibration solution is given in Figure 2 (attached). An example of a sample solution chromatogram from the experiment at 5.8 °C is shown in Figure 3 (attached). The calibration data for test item-standards is given in Figure 4 and Table 5 (attached).The r² fit was 1.0000 (optimum 1.0000). This reflects the suitability of the GC-system within the calibration range of 1.171 µg/mL to 93.648 µg/mL of the test item.
The good reproducibility and independency of the results from the flow rate led to the conclusion that the results of the vapor pressure determination of the test item Dehydrolinalool are reliable.

Applicant's summary and conclusion
- Conclusions:
- Calculation of the vapor pressure of Dehydrolinalool at 25 °C by interpolation based upon the simplified Clausius-Clapeyron equation resulted in a vapor pressure of
3.8 x 10E+1 Pa at 25 °C. - Executive summary:
During this study, the vapor pressure of the test item Dehydrolinalool has been determined using the gas saturation method. The vapor pressure of Dehydrolinalool was measured at test temperatures of 5.8 °C, 15.4 °C and 25.2 °C and was determined to be
5.0 x 100Pa at 5.8 °C
1.3 x 101Pa at 15.4 °C
4.0 x 101Pa at 25.2 °C
The vapor pressure of Dehydrolinalool at 25 °C was interpolated from the vapor pressure curve and was calculated to be
3.8 x 101Pa at 25 °C.
