Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- (Q)SAR
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- Estimations are based on the Antoine method, Modified grain method and Mackay method, MPBVP v1.43, using EPI Suite.
- Principles of method if other than guideline:
- Estimations are based on the Antoine method, Modified grain method and Mackay method, MPBVP v1.43. For the models, the estimated boiling point: 493.73 °C (4.3) and melting point 209.67 °C (4.2) are used.
- GLP compliance:
- not specified
- Type of method:
- other: estimated by calculation
- Specific details on test material used for the study:
- Calculation is based on the structure of sodium N-methyltaurinate
- Name of test material (as cited in study report): Ethanesulfonic acid, 2- (methylamino)-, monosodium salt - Temp.:
- 25 °C
- Vapour pressure:
- > 0 - < 0 Pa
- Conclusions:
- The vapour pressure of sodium N-methyltaurinate is approximately 5.78E-8 Pa at 25 °C.
- Executive summary:
The estimated values for the vapour pressure calculated by using the Antoine method, Modified Grain method and Mackay method differ in a range of > 1.07E-9 Pa and < 1.67E-7 Pa. All used models are calculated for an ambient temperature of 25 °C. From the model predictions, the Modified Grain method is selected to provide an appropriate value for the vapour pressure. The estimated value by the Modified Grain method is 5.78E-8 Pa and is between the estimations of the other two models. Thus, we consider the predicted value of 5.78E-8 Pa to provide a reliable approximation of the vapour pressure, since empirical data has not been observed.

Additional information
For the prediction of the vapour pressure, three different models are available, the Antoine method, Modified Grain method and Mackay method. The predictions vary from 1.07E-9 Pa to 1.67E-7 Pa. All calculations are based on ambient temperature of 25 °C. From the model predictions, the Modified Grain method is selected to provide an appropriate value for the vapour pressure. The estimated value by the Modified Grain method is 5.78E-8 Pa and is between the estimations of the two other models. We expect that the predicted value of 5.78E-8 Pa provides a reliable approximation of the vapour pressure, since empirical data have not been observed.
