Results and discussion
Vapour pressure
- Test no.:
- #1
- Temp.:
- 25 °C
- Vapour pressure:
- 0 hPa
- Remarks on result:
- other: calculated vapour pressure at 25°C: 1.31 x 10E-18 mm Hg ( 1.75 x 10E-18 hPa)
Any other information on results incl. tables
A vapour pressure of 1.31 x 10E-18 mm Hg (1.75 x 10E-18 hPa) at 25°C was calculated using EPIWIN v3.20, MPBPWIN v1.42. This is in agreement with the expected result because of the ionic structure of the molecule. Due to missing information about the applicability of the calculation model in respect to the substance under investigation the result should be treated with care.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of butanedioic acid, sulfo-, 4-(2-((1-oxo-10-undecenyl)amino)ethyl)ester, disodium salt was calculated using EPIWIN v3.20, MPBPWIN v1.42. The calculation yielded a vapour pressure of 1.31 x 10E-18 mm Hg (1.75 x 10E-18 hPa) at 25°C. This is in agreement with the expected result because of the ionic structure of the molecule. Due to missing information about the applicability of the calculation model in respect to the substance under investigation the result should be treated with care.
