Applicant's summary and conclusion
- Conclusions:
- The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of N-(2,2-dimethoxyethyl)acrylamide. The vapour pressure of the test substance at 20°C (293K) was 1.49 x 10^(-1) Pa = 1.11 x 10^(-3) mm Hg
- Executive summary:
The isothermal thermogravimetric effusion method was chosen for the determination of thevapour pressure of N-(2,2-dimethoxyethyl)acrylamide. The vapour pressure of the testsubstance at 20°C (293K) was 1.49 x 10-1Pa = 1.11 x 1 0 -3 mm Hg
