Any other information on results incl. tables
The vapour pressure of Myraldyl Acetate was sufficiently high at 20 and 25°C to be measured directly. The vapour pressure was measured at 15 to 30°C and a graph of LnVP vs 1/T generated is shown in Figure 11. The values were taken directly from the graphs for both tests. Comparison of the IR spectra for the untested material, tested and the sealed control, shown in Figure 12, revealed no differences and it is therefore concluded that Myraldyl Acetate did not degrade during the test.
Applicant's summary and conclusion
- Conclusions:
- The Vapour Pressure of Myraldyl Acetate was measured to be 0.0459 Pa at 20 °C and 0.0781 Pa at 25 °C.
