Additional information

A study was performed to determine the vapour pressure of the test substance according to OECD guideline 104 and EU method A.4. in compliance with GLP using the effusion method (vapour pressure balance).

The vapour pressure was measured in the temperature range of 33 to 142 °C. In the range of 33 to 94 °C the vapour pressure was below the lower detection limit of 10-5 hPa. In the temperature range of 104.4 to 141.7 °C a vapour pressure could be measured.

The vapor pressure of Reactive Red F00-0124 was afterwards calculated, using the Antoine constants, to 3.4x10-9 hPa at 20 °C, 6.4x10-9 hPa at 25 °C, and 1.2x10-7 hPa at 50 °C.
