Vapour Pressure

The vapour pressure ofthe test substance was found to be 0.00011 Pa at 20°C and 0.00017 Pa at 25 °C. The full results are shown inTable 2 (attached) and the Ln VP vs 1/T plot shown in Figure 14 (attached). There were no differences between the IR spectra for the untested, control and tested material, the comparative spectra are shown in Figure 15 (attached). Therefore the test substance was considered to be unchanged during the test.No claim of GLP compliance will be made for the IR data but as it has simply been used as qualitative data to confirm stability of the test substance, by comparison of spectra, it has been reported here.

Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test substance was determined to be 0.00011 Pa at 20 °C, under the conditions of the test.
The vapour pressure of the test substance was determined to be 0.00017 Pa at 25 °C, under the conditions of the test.
Executive summary:
