EC number: 941-167-8
CAS number: 1584709-99-8
test item showed no thermal effects up to the maximum test temperature
of 300 °C.
vapour pressure was measured in the temperature range of 86.1 to 181.8°C.
4.6/1: Results of the dynamic method
Vapour pressure (hPa)
the measured data points of the vapour pressure curve, the constants A,
B and C of the Antoine equation
P = A + B / (C+T)
be derived by regression:
vapour pressure of the test item calculated by extrapolation of the
measured vapour pressure curve for the temperatures 20, 25 and 50 °C
were 0.36, 0.50 and 2.34 hPa, respectively.
vapour pressure of the test substance was measured under GLP according
to OECD 104 / EU A4 guideline by dynamic method.
preliminary stability test by DSC showed no thermal effects up to the
maximum test temperature of 300 °C.
series of nine measurements was recorded between 15 and 480 hPa,
corresponding to 86 to 182°C. The vapour pressure of the test item was
extrapolated from the regression to be 36 Pa at 20°C, and 50 Pa at 25°C.
(extrapolated) Low volatility.
A reliable experimental study, conducted
according to a recognized OECD/EU method, is available. Despite minor
restrictions for accuracy, due to distant extrapolation, it is
considered as a key study. The result is retained as key data.
