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:
- other information
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- differential thermal analysis (screening DTA, isotherm DTA)
- GLP compliance:
- no
- Specific details on test material used for the study:
- The thermal stability of 2,3-Dichlornitrobenzol should be investigated with the differential thermal analysis (DTA) considering the follow storage conditions:
- Type of container / packaging: company container (iron)
- Pack size: 60 m³
- Study duration: up to 6 month
- Temperature: up to 100 °C
- atmospheric pressure: normal (1013 mbar)
- max. medial heating temperature 135 °c
ANALYTICAL METHODS
- Analytical method used:
1. Screening DTA (3K/ min) additons: steel (St37),iron, rust;
2. Isotherm DTA (310°C isotherm, DTA 320°C isotherm, DTA 330°C isotherm, DTA 340°C isotherm, DTA 350°C isotherm, DTA 360°C isotherm)
- Executive summary:
The presence of steel (St37), iron or rust at screening DTA has no significant influence on the decomposition reaction.
It has resulted a TMR (Time to maximum rate; circa 1 year) only on 190°C.
The storage up to 100 °C in a company container of 60 m³ is uncritical up to 6 month.
Reference
Sample shows at screening DTA (heat rate 3 K/min) in a closed glass vessel above 300°C a strong exothermic decomposition reaction with a heat release of >1500 kJ/kg.
The presence of steel (St37), iron or rust at screening DTA has no significant influence on the decomposition reaction.
It has resulted a TMR (Time to maximum rate; circa 1 year) only on 190°C.
The storage up to 100 °C in a company container of 60 m³ is uncritical up to 6 month.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
