- Conclusions:
- The test method's lower limit of detection was determined and used to calculate an upper limit vapor pressure value. Based on the 50°C run, the vapor pressure for the Substance was determined to be <4.30 x 10-6Pa for temperatures up to 50°C
- Executive summary:
The vapor pressure of the Substance was determined employing the procedure outlined in the Organization for Economic Co-operation and Development (OECD) Test Guideline 104: "Vapor Pressure - Gas Saturation Method" and EU directive 67/548 EEC Method A.4 "Vapor Pressure". The vapor pressure of a test substance is a significant factor for predicting atmospheric concentrations.
A stream of nitrogen was passed over the test substance in such a way that the nitrogen became saturated with the test substance vapor which was then collected onto a suitable absorbent trap. Measurement of the amount of the test substance transported by a known amount of carrier gas was used to calculate the vapor pressure at a given temperature. Evaluation of the Substance at 40°C for 24 hours and 50°C for 48 hours showed no measurable vapor pressure. The test method's lower limit of detection was determined and used to calculate an upper limit vapor pressure value. Based on the 50°C run, the vapor pressure for the Substance was determined to be <4.30 x 10-6Pa for temperatures up to 50°C.

The system offset pressure using a molecular weight of 368.551 g/mol was 5.3145 x 10-5Pa. The calculated mean measured vapor pressure of the test substance by the SRG method, using a molecular weight of 368.551 g/mol, was 1.49 x 10-3Pa at 20 ± 1°C. The measured vapor pressure ranged from a minimum of 1.21 x 10-3Pa to a maximum of 1.79 x 10-3Pa. Individual and mean measured vapor pressures and out-gassing rates for the test substance at 20 ± 1°C using a molecular weight of 368.551 g/mol are presented in the table below.
