- Vapour pressure:
- 0.16 Pa
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure at 20°Cwas calculated from the average headspace concentration using equation 1 ( see paragraph 3.4 in th attached report).
The chromatograms recorded in the present study were compared with the GC-MS chromatograms of a standard quality. With the structure asigments therein it was possible to assign the major peak contributing to the vapour pressure of the test material to an empirical formula of C15 H22O, corresponding to a molecular weight of 218.33 g/mol and 220.35 g/mol. therefore a representative molecular weight of 218.33 g/mol was used for the calculation of the vapour pressure. The result was 0.16Pa. Therefore: Vapour pressure of Akigalawood: 0.16Pa at 20°C
