Test item



 ≤ 4.8 e-8



≤ 3.6 e-10



≤ 1.2 e-7



≤ 9.3 e-10


Conclusions:
The vapour pressure of the test item at 20℃ (293K) and 25℃ (298K) was ≤ 4.8 e-8 Pa and ≤ 1.2 e-7 Pa, respectively.
Executive summary:

The isothermal TGA effusion method was applied for the determination of the vapour pressure of test item according to OECD 104.


The weight losses of the test item had to be determined at temperatures above the melting temperature of the test item. According to this, the vapour pressure of the test item (which was, according to the method, extrapolated to 20℃ and 25℃) could be slightly overestimated and is reported as less than or equal to values.


The vapour pressure of the test item at 20℃ (293K) and 25℃ (298K) was ≤ 4.8 e-8 Pa and ≤ 1.2 e-7 Pa, respectively.
