Boiling Point / Boiling Range (DSC)

Two measurements in aluminium crucibles with a hole showed broad endothermic signals. Due to the broad shape of the endothermic signals only temperature ranges but no defined onset temperatures can be derived. A correctionof the values to standard atmospheric pressure wasdeemed unnecessarybecause theatmospheric pressure during the tests was 1022 hPa and therefore the resulting correction is much smaller than the uncertainty that accompanies the evaluation of the broadendothermic signals.

The measurements showed a broad endothermic effect in the temperature range 70 °C to 380 °C.

Ident-No.

According to the information from the sponsor the test item consists of a large number of different chemical substances. This composition from many chemical substances of the test item is most likely the reason that no distinctive boiling point could be observed.

The test item has a boiling range at atmospheric pressure (1013.3 hPa) ofapproximately 70 °C to 400 °C.

Applicant's summary and conclusion

Conclusions:
The test item has a boiling range at atmospheric pressure (1013.3 hPa) of 70 °C to 400 °C.
Executive summary:

The test item has a boiling range at atmospheric pressure (1013.3 hPa) of 70 °C to 400 °C.
