- Executive summary:
The vapour pressure of the test material was conducted in a study performed to the standardized guideline OECD 104 under GLP conditions. The vapour pressure of the test material at 18°C (290 K) has been determined to be less than 0.07 torr (10 Pa), the lower limit for the static method used.
Reference
At room temperature, the test material was allowed to equilibrate in the water bath for 25 minutes. The test temperature was measured to be 18°C (290 K). Three sets of triplicate readings were obtained at 9 to 25 minute intervals over 45 minute periods. At 18°C, the nine vapour pressure readings were determined to be at the limit of detection of the test system, 0.07 torr (10 Pa). No vapour pressure was measured for the test material at room temperature (18°C).
At 50°C, three experiments were performed. The water in the water bath evaporated to dryness during the first 50°C experiment. The experiment was initiated a second time, equilibrating to test temperature for 20 minutes. The experiment was aborted due to the air not being evacuated prior to initiation of the vapour pressure readings. The air was then evacuated and the first reading taken after approximately 2.5 hours. Seven vapour pressure readings were then taken at 5 to 20 minute intervals within a final period of approximately 1 hour. Six temperature measurements of 50°C confirmed the test temperature was maintained. The mean measured vapour pressure (± standard deviation) of the test material at 50°C (320 K) was determined to be 2.0 (± 0.28) torr (n=9), equivalent to 268 ± 37 Pa.
The test system was then warmed to 80°C, and allowed to equilibrate to test temperature for 20 minutes. Eleven vapour pressure measurements were obtained at 8 to 13 minute intervals over a period of approximately 1.5 hours. The mean measured temperature (± standard deviation) was 79°C (± 0.74°C) (n=8). Vapour pressure measurements generally ranged from 2.9 to 4.4 torr (387 to 592 Pa). The mean measured vapour pressure (± standard deviation) of the test material at 79°C (350 K) was determined to be 3.7 torr (± 0.55 torr) (n=10), equivalent to 488 ± 73 Pa.
