Additional information

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 substance. The vapour pressure of the test substance was measured using the static method. In a temperature range of 15.6 – 57.0 °C eleven pairs of temperature/vapour pressure values were measured. The values of the heating and cooling down phase showed good correspondence and correlated well with the values which were measured in the experiment. Therefore, the result of the study is considered valid. The measured values for pressure P and temperature T were used to calculate pairs of log P and 1/T. These values were plotted, from the linear regression, vapour pressures at ambient temperature were determined.

The vapour pressures of the substance was determined to be 52 Pa at 20 °C and 69 Pa at 25 °C respectively.
