TGA EXPERIMENT

From 175°C upwards the weight of the sample decreased significantly. At 271°C the sample weight had decreased by 25%. After the experiment it was observed that the test item was evaporated from the sample container.

 

DSC EXPERIMENT 1

An endothermic peak between 25°C and 75°C was observed. The extrapolated onset temperature of the peak was 60.88°C. The effect was most likely obtained due to melting of the test item. Another endothermic effect was observed between 200°C and 325°C. The extrapolated onset temperature of the peak was 245.89°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.

DSC EXPERIMENT 2

With the first heating the extrapolated onset temperature of the melting peak was 61.26°C. During cooling an exothermic peak was observed between 45°C and 55°C. The effect was obtained due to crystallization of the test item. With the second heating an extrapolated onset temperature of 59.38°C was obtained. The results demonstrated that the endothermic effect was due to melting of the test item. Another endothermic effect was observed between 200°C and 325°C. The extrapolated onset temperature of the peak was 245.78°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.

DSC EXPERIMENT 3

The extrapolated onset temperature of the melting peak was 61.52°C. The extrapolated onset temperature of the boiling peak was 320.68°C. The endothermic peak shifted to higher temperatures. It 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.

DSC EXPERIMENT 4

Similar results to Experiment 1 were obtained. The extrapolated onsets of the melting and boiling peaks were (respectively) 61.35°C and 245.38°C. After the experiment it was observed that the test item had evaporated from the sample container.

KEY RESULT

The boiling temperature of the substance was determined as the average boiling temperature obtained from Experiment 1 (245.89°C) and Experiment 4 (245.38°C).

Conclusions:

The boiling temperature of the substance Cyclopentadecanone at 1004 hPa was determined to be 246°C.

Executive summary:

The boiling temperature was determined using Differential Scanning Calorimetry in a GLP study according to EC A.2, OECD 103 and OPPTS 830.7220.

The boiling temperature of the substance Cyclopentadecanone was determined in duplicate obtaining a mean value of 246°C.

Description of key information

The boiling temperature of the substance was determined to be 246°C.
