EC number: 242-056-0
CAS number: 18171-19-2
Measured value (°C)
Corrected value (°C)
*the mean value is calculated from
test 1 and 2 and rounded to ±0.5°C.
Determination of the corrected
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
Flash Point: 41 - 70°C (ISO 3679)
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
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.
