Results and discussion
Vapour pressure
- Key result
- Temp.:
- ca. 298 K
- Vapour pressure:
- < 2.35 other: x10E-24 Pa
- Remarks on result:
- other: Calculation based on a boiling point of 748°C of the component of the test substance with the smallest molecular weight, which has the highest vapour pressure.
Any other information on results incl. tables
Based on the calculated boiling points for the three representative compounds in the test item and using the modified Watson correlation, the vapour pressure of the compounds were calculated as follows: Table 1: Individual vapour pressures of the representative compounds of the test item
Compound | Vapour pressure [Pa] |
Compound I | 2.35 x 10EXP-24 |
Compound II | 5.20 x 10EXP-26 |
Compound III | 1.22 x 10EXP-27 |
Applicant's summary and conclusion
- Conclusions:
- Based on the modified Watson Correlation in Annex of the OECD Guideline No. 104, the vapour pressures of the test substance is smaller than
2.35x10e-24. - Executive summary:
The estimation of the vapour pressure of the test item was based on the EEC directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.4 "Vapour Pressure", EEC Publication No. L383, December 1992 and the OECD Guideline No. 104, ''Vapour Pressure", adopted July 27, 1995.
The boiling point of the component with the smallest molecular weight of the test substance was calculated to be approximately 478°C using Meissner's method. The vapour pressure was estimated for the three main components based on the boiling point calculated and using the Modified Watson Correlation. For the component with the smallest biling point the vapour pressure was calculated as 2.35x10e-24 Pa. Therefore, the vapour pressure of the test substance is smaller than 2.35x10e-24 Pa.
