Preliminary test

From the start of the experiment the weight of the sample decreased significantly. At 59°C the sample weight had decreased by 25%. After the experiment it was observed that the test item was evaporated from the sample container.

Main study

During cooling no effects were observed which were due to crystallization of the test item. During heating an endothermic peak between 0°C and 100°C was observed. The extrapolated onset temperature of the peak was 67.461°C. The effect was most likely obtained due to boiling of the test item. After the experiment it was observed that the test item had evaporated from the sample container.

To further investigate the endothermic peak between 0°C and 100°C a closed sample container was applied in the Experiment 5. Figure 3 shows the DSC-curve obtained in Experiment 5. The extrapolated onset temperature of the boiling peak was 106.758°C. It was observed that the endothermic peak had shifted to a higher temperature which demonstrated that boiling of the test item was the reason for the endothermic effect. After the experiment it

was observed that the test item had evaporated from the sample container.

Experiment 6 was performed as a duplicate of boiling point temperature determination of the test item. The temperature program was the same as that used in Experiment 4. The extrapolated onset of the boiling peak was 66.978°C. After the experiment it was observed that the test item had evaporated from the sample container.

The boiling temperature was determined as the average boiling temperature obtained from Experiment 4 (67.461°C) and Experiment 6 (66.978°C).

Conclusions:
The boiling temperature of AsahiklinTM AC-2000 was determined to be 67°C (340K) by using DSC. The atmospheric pressure was 1014 ± 1 hPa.
Executive summary:

The boiling temperature of AsahiklinTM AC-2000 was determined to be 67°C (340K) by using DSC. The atmospheric pressure was 1014 ± 1 hPa.
