77.1 °C
Atm. press.:
1 013.25 hPa
Decomposition:
no
Sublimation:
no
Conclusions:
The mean value out of all measurements of the melting point of the test item was determined to be 77.1 °C (350.3 K).
Executive summary:

The melting temperature of the test item was determined according to EPA-Guideline 830.7200 and EEC-Guideline 92/69/EEC A.1, capillary method. Therefore, samples of the test substance were filled into melting point capillaries. These samples were exposed to a temperature/time-gradient while the intensity of the light beam which was directed trough the sample was recorded. The test was performed three times. The mean value out of all measurements of the melting point of the test item was determined to be 77.1 °C (350.3 K).

Description of key information

The melting point of the test item was determined to be 77.1 °C with the capillary method.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
77.1 °C
