Results
The thermograms of the DSC runs PN11227 and PN11230 show in the temperature range of 110 – 250 °C an endothermic effect (boiling) could be detected.
During the heating phase the test item showed an endothermic signal in the temperature range of approx. 110 – 250 °C that can be associated with the boiling of the test item. For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 7 (e.g. Ethylene glycol). A correction value φ = 6.15 was used for the temperature of 200 – 210 °C. The lowest measured onset temperature is corrected to the standard pressure to be 209.19 °C and the highest onset temperature to be 210.16 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 209.68 °C, the test item has a boiling point of 209.7°C.
