The determination of the vapour pressure of the test item was performed in accordance with the OECD guidelines for the Testing of Chemicals, guideline No. 104 “Vapour Pressure”, using a Cottrell ebulliometer. The test was performed at a pressure range from 48 to 125 mbar. The test was performed in triplicate. The Antoine coefficients were fitted to the measured data with the least square method.
Antoine coefficients log(p/mbar) = 9.659 – 3534.532/(304.836 + T(°C))
The boiling point was determined according to OECD TG 104 with an Cottrell ebulliometer. The boiling temperature of the test substance was found to be 226 ± 5 °C (1013.25 mbar)(calculated by extrapolation).
The test substance is thermally not stable at ambient pressure; it decomposes before the normal boiling point is reached.
