EC number: 430-150-6
CAS number: -
test substance being a liquid at room temperature, a preliminary test
was performed, increasing the temperature by steps of 50 °C until an
approximate boiling point was observed, i.e. ca. 218 °C.
temperature of the heating bath was set ca. 200 °C, and a heating rate
of the bath of 1 °C/minute is applied.
4.3/1: Boiling point – results
Boiling point, as observed, non-corrected
1 (± error)
217.9 °C ± 0.1
2 (± error)
218.0 °C ± 0.1
3 (± error)
218.3 °C ± 0.1
Mean ± standard deviation
218.1 °C ± 0.2
rough values are corrected by:
the calibration correction of the thermometer,
the emerging column correction,
the barometric pressure correction, using a value of the factor
calculated by interpolation of literature factors of reference
substances which have their boiling point slightly higher, respectively
lower, than the test substance, i.e. terbutyltoluene and
diethyleneglycol mono n-butyl ether
boiling point of the test substance was determined under GLP according
to OECD 103/EU A2 guideline, Siwoloboff (capillary) method. Three
main runs were performed, and the mean final
temperature was retained.
boiling temperature of the test substance has been determined to be 218.1°C
under 100.28 kPa, and 219.4°C as corrected to normal atmospheric pressure.
Measured boiling point = 218.1°C under 100.28 kPa; Corrected boiling point = 219.4°C at normal atmP
A fully reliable experimental study, conducted according to a recognized
OECD/EU method, is available. It is considered as a key study, and the
result is retained as key data.
