- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0 hPa
- Remarks on result:
- other: vapour pressure balance method
- Conclusions:
- The vapour pressure of TCPP is 0.000014 hPa at 25°C.
- Executive summary:
The vapour pressure of TCPP is 0.000014 hPa at 25°C, obtained in a study conducted in accordance with the EU.method A.4.
A sequence of runs was started after a sample of test material had been under vacuum for approximately 12 minutes. Temperature and pressure readings were taken between 50 and 65°C with a one hour dwell at 50°C between runs.
Linear regression analysis used to calculate the vapour pressure at 25°C.
