Storage stability and reactivity towards container material
Administrative data
Link to relevant study record(s)
- Endpoint:
- storage stability and reactivity towards container material
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Guideline study with acceptable restrictions.
- GLP compliance:
- yes
- Type of method:
- other: Screening procedure and Digital Thermal Analysis (DTA)
- Results:
- Self-reactive substances
SADT > 75 °C, not self reactive
heat of decomposition: - 380 J/g - Conclusions:
- The self-reactive substances showed a SADT >75 °C and it is therefore not self reactive.
- Executive summary:
The determination of self-reactive substances was measured at screening procedure and showed a heat of decomposition of -380 J/g. The measuration of Digital Thermal Analysis (DTA) showed following result: A weak exothermic reaction (-10 J/g) was detected at 80 °C. Above 321 °C began a exothermic reaction (> -380 J/g), which was not completed until 500 °C. The first exothermic reaction was an oxidizing reaction with the residual oxygen in the glass container. It disappears under argon.
Based on the onset-temperature (321 °C) it is expected that SADT is > 75 °C and it is therefore not self reactive.
Reference
DTA (3 K/min):
A weak exothermic reaction (-10 J/g) was detected at 80 °C.
Above 321 °C began a exothermic reaction (> -380 J/g), which was not completed until 500 °C. The first exothermic reaction was an oxidizing reaction with the residual oxygen in the glass container. It disappears under argon.
Based on the onset-temperature (321 °C) it is expected that SADT is > 75 °C.
Description of key information
The self-reactive substances showed a SADT >75 °C and it is therefore not self reactive.
Additional information
The determination of self-reactive substances was measured at screening procedure and showed a heat of decomposition of -380 J/g. The measuration of Difference Thermal Analysis (DTA) showed following result: A weak exothermic reaction (-10 J/g) was detected at 80 °C. Above 321 °C began a exothermic reaction (> -380 J/g), which was not completed until 500 °C. The first exothermic reaction was an oxidizing reaction with the residual oxygen in the glass container. It disappears under argon.
Based on the onset-temperature (321 °C) it is expected that SADT is > 75 °C and it is therefore not self reactive.
