Preliminary test

From the TGA curve it could be derived that the weight of the sample decreased significantly at 80°C.

At 108°C the sample weight has decreased by 25%. After the experiment it was observed that the test

item was evaporated from the sample container.

Main tests

During the first experiments, no effects were observed during cooling due to crystallisation. During heating an

endothermic peak between 75°C and 125°C was observed. The extrapolated onset temperature of the peak was 114.579°C. The effect was most likely obtained due to evaporation of the test item. After the experiment it was observed that the test item had evaporated from the sample container.

In the second experiment a higher heating rate (50°C/min) was used. The extrapolated onset temperature was 114.532°C. The endothermic effect had not shifted to higher temperatures.

It demonstrated that boiling of the test item caused the endothermic effect. Since a higher heating rate was used, the extrapolated onset temperature was not used in the calculation of the boiling point.

A third experiment was performed to obtain a duplicate value for the boiling temperature of the test item.

The temperature program was similar as the heating program of the first experiment. The extrapolated

onset of the evaporation peak was 114.144°C. After the experiment it was observed that the test item

had evaporated from the sample container.

To further investigate the melting temperature of the test item, two subsamples of the test item were

stored for 18 hours at -19.3 ± 0.6°C and at -83.5 ± 1.6°C respectively. It was observed that after storage

the test item was still a liquid.

The boiling temperature was determined as the average boiling temperature obtained from Experiment 1 (114.579°C) and Experiment 3 (114.144°C).

Applicant's summary and conclusion

Conclusions:
The boiling temperature of Cyclopentylchloride was determined to be 114.4°C (387.5K) by using DSC.
