Key result

Boiling pt.:

311.6 °C

Atm. press.:

1 013.25 hPa

Five assays were performed during the test, the temperature values obtained for the corrected boiling point varied between 305.8 and 313.9 °C. The mean value for the boiling point is explained as the mean of at least two assays for which the the boiling point value are in the range of the estimated accuracy of the method: ± 0.5 °C up to 326.9 °C and ± 2.0 °C above 326.9 °C.

The assays No. 3 and 5 were taken into account for the boiling point.
