Applicant's summary and conclusion
- Conclusions:
- Based on the measured vapour pressures in the temperature range 78 to 117°C, the vapour pressure of the test substance at 20, 25, and 50°C was calculated using the Antoine equation. The calculated vapour pressures at 20, 25, and 50°C were determined to be 0.0000058, 0.00001, and 0.00013 Pa, respectively.
- Executive summary:
The vapour pressure of pyridiniumsulfonate was investigated in a study conducted according to EU Method A.4 (Vapour Pressure; 2008) and OECD Guideline 104 (Vapour Pressure Curve; 2006) via the effusion method (vapour pressure balance). The vapour pressure of the test substance was determined in the temperature range 78 to 117°C (vapour pressure measured for nine temperatures) . Based on the measured data in the temperature range 78 to 117°C, the vapour pressures of the test substance at 20, 25, and 50°C were calculated to be 0.0000058, 0.00001, and 0.00013 Pa, respectively.
