Because the flash point of the pre-test and
the flash point of the main study differed by less than 2 K, no further
testing was necessary.
The flash point at standard pressure
was calculated using the following equation.
F = C + 0.025 * (1013 – P)
C = measured temperature in °C
P = measured atmospheric pressure in
F = flash point at 1013.25 hPa in °C
Table 1 Result
Measured Flash point in °C
Pressure in hPa
Corrected Flash point in °C
According to ISO 13736, the value
should be rounded to 0.5 K.
Therefore, the flash point is stated
as -4.5 °C.
The flash point of reaction
mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA)
was determined with -4.5 °C (value corrected to standard pressure), this
value is the mean of two independent determinations.
The flash point (following Abel -
Closed Cup) is -4.5 °C.
The flash point of “2-propanol and 2-butanol production, distn.
residues” was measured under GLP and according to the test guideline EU
A.9. The mean of two independent determinations at standard pressure was
As the boiling point was determined being 70 - 122 °C, the
“2-propanol and 2-butanol production, distn. residues” is classified
with F, R11 (highly flammable) according to DPD or as flammable liquid
cat. 2, H225 (highly flammable liquid and vapor) according to the CLP
