- Executive summary:
A study was conducted to determine the thermal stability of the test substance according to the Accelerated Rate Calorimeter (ARC) method. When heated, the test substance produced two small exotherms with onset detected at ~124°C and ~130°C with an adiabatic temperature rise lower than 3°C. The heat-wait-search was continued after the exotherm was completed. A highly energetic exotherm occurred with onset detected at ~160°C, attributed to the thermally initiated polymerization of the material followed by gassy decomposition. Onset of gas generation coincided with the onset of the main exotherm. Under the study conditions, the thermal stability of the test substance was modified at 124, 134, and 160°C (Martens, 2004).
Reference
Heating the test substance in an ARC produced two small exotherms with onset detected at ~124°C and ~130°C with an adiabatic temperature rise lower than 3°C. Continuing the test after the exotherms were completed resulted in a highly energetic exotherm with onset detected at ~160°C, attributed to the thermally initiated polymerization of the material followed by gassy decomposition. Onset of gas generation coincided with the onset of the main exotherm.
The ARC run utilized the following test conditions, and produced the following results:
Material tested | Test substance |
Run No. | ARC-10975A |
Run type | Heat Wait Search |
O Factor | 1.6047 |
Test Cell | Stainless |
Exothermic Onset Detection Temp, °C | 124; 130; 160 |
DeltaH, -kJ/kg (1) | 2.8 (between 1 and 284) (2) |
Adiaatic DeltaT, °C | 1.3 (between 1 and 135) (2) |
Temperature range in test, °C | 30 -326 (2) |
Gas generation onset temperature, °C | ca. 170 |
Cool down pressure, bara | 41.2 |
(1) Heat release calculations are based on an estimated heat capacity of 2.1 kJ/(kg°K)
(2) Test was automatically stopped before the decomposition exotherm was completed since 50 bar pressure limit was reached.
Description of key information
The thermal stability of the test substance was determined according to the Accelerated Rate Calorimeter (ARC) method (Martens, 2004).
Additional information
The test substance produced two small exotherms at 124 and 130°C and an highly energetic exotherm at 160°C (attributed to thermally initiated polymerisation and decomposition).
