Any other information on results incl. tables
Due to the fact that the test item showed no proper linear correlation of the vapour pressure and the inverse temperature 1/T, the Antoine constants could not be evaluated in the measured temperature range. Therefore, the vapour pressure was estimated according to the measured vapour pressures for the temperatures 20, 25 and 50 °C.
The measured vapour pressure values together with the measured temperatures are listed in the table in the next section "overall remarks".
Applicant's summary and conclusion
- Conclusions:
- The test item ß-NADH, disodium salt (CAS no. 606-68-8) showed no evaluable vapour pressure curve in the temperature range of 35 to 66 °C. Due to this result, the vapour pressures for the temperatures 20, 25 and 50 °C are estimated on the basis of the maximum measured vapour pressures, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline 104 (2006). The estimated vapour pressure of the test item is < 0.0073 hPa at 20°C, 25°C and 50°C.
- Executive summary:
The test item ß-NADH, disodium salt (CAS no. 606-68-8) showed no evaluable vapour pressure curve in the temperature range of 35 to 66 °C. Due to this result, the vapour pressures for the temperatures 20, 25 and 50 °C are estimated on the basis of the maximum measured vapour pressures, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline 104 (2006). The estimated vapour pressure of the test item is < 0.0073 hPa at 20°C, 25°C and 50°C.
