Determination of the corrected flash-point:
Tc = T0 + 0.25 x (101.3 – p)
TC = corrected flash point to the standard atmospheric pressure (101.3 kPa)
T0 = measured flash point at actual atmospheric pressure
p = actual atmospheric pressure [kPa]
Description of key information
Flash Point: 41 - 70°C (ISO 3679)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 41 °C
Additional information
Several measured flash points are available for the substance. A measured flash point of 57.5°C at 1013 hPa was determined for the registered substance using a rapid equilibrium method in accordance with ISO 3679 Test Method (Haas 2011). In addition, flash point values of 41°C, 57°C and 70°C were determined for the substance using a rapid equilibrium method in accordance with ISO 3679 Test Method (Wacker 2008).
Variations in the flash point values may be caused by variations in purity of the test substance and in the test method used. In particular, the presence of higher concentrations of volatile impurities such as methanol (a hydrolysis product of the substance) can result in lower flash points. The reliable values are used as weight of evidence. Each registrant will classify their product accordingly.
In available secondary sources to which reliability could not be assigned, flash point values of 46°C and 67°C were reported for the substance.
Flash point values of 41°C, 57°C and 57.7°C, indicate that the substance should be classified for flammability (Category 3) in accordance with the criteria of Regulation (EC) No. 1272/2008.
Flash point value of 70°C indicates that the substance should not be classified for flammability in accordance with the criteria of Regulation (EC) No. 1272/2008.
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).
