EC number: 700-720-1 | CAS number: -
The vapour pressure was measured in the temperature range of 18 °C to 121 °C. Above 42 °C a vapour pressure was measured. The test item melted during the test. Values between 64 °C and 81 °C show deviations which are presumably caused by the melting process and were therefore excluded from the evaluation.
A figure shows the vapour pressure (logarithmic scale) as a function of the inverse temperature (1/T, T in Kelvin). For better readability the temperature is reported in a centigrade scale. The values for 20, 25 and 50 °C are calculated, using the Antoine constants A, B and C as shown.
T / °C
p / hPa
log (p/hPa) = A + B/(C+T[°C])
A = 5.82562
B = -3554.43
C = 273.15
The vapour pressure of the test substance was measured in a guideline study (EU A.4; OECD TG 104) with a vapour pressure balance (effusion method). The test substance has a vapour pressure of 8.0 x 10E-5 Pa at 25 °C.
