Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Transition of State
The material underwent a phase change during the test. It changed from solid to liquid at approximately 18 ºC under reduced pressure, as the temperature increased in the test.
The point of solidification was noted to be below 15 ºC, during the cooling phase before the test start.
The vapour pressure has been presented for two standard temperatures (20 °C and 50 °C) using the Log P Vs 1/T trend line from two stable sections of the data set, both in the liquid phase.
| Log P Vs 1/T trend line | Calculated Vapour Pressure | |||||
| Temperature range used (K) | Intercept | Slope | Temperature (ºC) | Temperature (K) | Log P | Vapour pressure (Pa) |
| 293.85 - 298.05 | 0.00430 | -0.00034 | 20 | 293.15 | 2.59 | 391 |
| 302.65 - 323.75 | 0.00521 | -0.00066 | 50 | 323.15 | 3.23 | 1680 |
Calculated Vapour Pressure of [trade name] 5372 at:
20°C (293.15 K, liquid phase) = 391Pa
50°C (323.15 K, liquid Phase) = 1680Pa
Description of key information
20°C (293.15 K) = 391 Pa (OECD 104, static method)
50°C (323.15 K) = 1680 Pa (OECD 104, static method)
Key value for chemical safety assessment
- Vapour pressure:
- 391 Pa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
