- Specific details on test material used for the study:
- Name sodium 3-sulfobenzoate
Batch no. 170103
CAS No. 17625-03-5
Purity > 99.0% (Titration with NaOH, Glass indicating electrode, Calomel reference electrode)
Expiry date 14. Feb. 2019
Storage Room Temperature (20 ± 5°C), keep away from humidity - Test no.:
- #3
- Temp.:
- 60 °C
- Vapour pressure:
- 0.003 Pa
- Conclusions:
- Vapour pressure of sodium hydrogen m-sulphonatobenzoate at 60 °C is 3.19 x 10-3 Pa.
- Executive summary:
Vapour Pressure of sodium 3-sulfobenzoate has been determined accordin to OECD 104 and EU A.4 using the effusion method Knudsen Cell.
The vapour pressure was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible or relevant weight loss. As a calculation on base of the measured weight losses is not possible, the highest vapour pressure, derived from all measurements, is stated as limit value. Vapour pressure of sodium hydrogen m-sulphonatobenzoate at 60 °C is 3.19 x 10 -3 Pa.
Reference
The vapour pressure was examined at nine different temperatures. No temperatures could be evaluated as they showed no reproducible or relevant weight loss. As a calculation on base of the measured weight losses is not possible, the highest vapour pressure, derived from all measurements, is stated as limit value. Vapour pressure at 60 °C: 3.19 * 10-03 Pa.
