Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

In accordance with EU A4 Regulation (EC) No 440/2008, Annex, Official Journal of the European Union L142/1, vapour pressure is measured using a modified static method (OECD Guidelines for The Testing of Chemicals, 104, March 23, 2006). The modification being that a direct reading MKS Baritron Capacitance Manometer Model 628C was substituted for the mercury manometer in the method. Water bath temperature was measured using a NIST traceable digital thermometer readable to 0.1° (Certificate # A247308, retest date 11-21-2018).

Vapour pressure of the test substance was determined at 4 temperatures:

10 °C:       586.5 Pa

21.1°C:     959.8 Pa

50 °C:       1493.0 Pa

80 °C:       2066.2 Pa

Key value for chemical safety assessment

Vapour pressure:
959.8 Pa
at the temperature of:
21.1 °C
