Results and discussion

Melting / freezing point
Melting / freezing pt.:
-29 °C
Atm. press.:
101.3 kPa

Any other information on results incl. tables

A broad endothermic peak between about -100°C and -22°C indicates the melting of the test item. An endothermic peak starting at about 84°C shows vapourisation of the test item. The test item was heated upto 300°C and exothermic decomposition was not observed.

Applicant's summary and conclusion
