EC number: 949-569-5 | CAS number: -
The vapour pressure was measured in the temperature range of 109.6 to 148.1 °C.
Results of the dynamic method
Temperature / °C
Vapour pressure/ hPa
From the measured data points of the vapour pressure curve the constants A, B and C of the Antoine equation was derived by regression of the data points to A = 12.0288; B = -3371.47; C = 273.15. The vapour pressure of the test item was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50°C.
Calculated vapour pressure values for 20, 25 and 50 °C
Vapour pressure / hPa
A study was conducted according to OECD TG 104, Regulation (EC) No 440/2008 method A.4 to determine the vapour pressure of the test item. A vapour pressure curve with 9 data points was measured over a pressure range between 15.2 to 37.8 hPa. For control 3 measuring points were evaluated with decreasing pressure. The vapour pressure was measured in the temperature range of 109.6 to 148.1 °C. From the measured data points of the vapour pressure curve the constants A, B and C of the Antoine equation was derived and the vapour pressure of the test item was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. The vapour pressure was determined to be 3 Pa at 20 °C, 5 Pa at 25 °C and 39 Pa at 50 respectively.
The vapour pressure of the test item was determined to be 3 Pa at 20 °C, 5 Pa at 25 °C and 39 Pa at 50 °C respectively.
