Applicant's summary and conclusion

Conclusions:
The isothermal TGA effusion method was applied for the determination of the vapour pressure of t-Butyldiethanolamine.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was:
20°C 25°C
[Pa] [mm Hg] [Pa] [mm Hg]
Test item 0.20 1.5 x 10-3 0.36 2.7 x 10-3
