Test material

Reference
Name:
Unnamed
Type:
Constituent
Details on test material:
- Name of test material (as cited in study report): 2,3-Dichlornitrobenzol
- Analytical purity: no data
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)



Results and discussion

Any other information on results incl. tables

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.
