Additional information

In a GLP study, conducted according to OECD guideline 104/EU method A4, an attempt was made to measure the vapour pressure of the test material using the static method.

Over the temperature range of 29 to 70 °C no vapour pressure above background (approx. 65 Pa) could be measured. Therefore, the vapour pressure was calculated by a modified Watson method, based on the measured boiling point of the material of 399 °C.

The calculated vapour pressure was 0.00013 Pa at 20 °C and 0.00025 Pa at 25 °C. These calculated values explain the failure to measure a vapour pressure for the test material by the static method, which is recommended for vapour pressures in the range 10 to 105 Pa.
