- Conclusions:
- Under the study conditions, test substance showed two endothermic effects, the first at the temperature range 30 – 45°C and the second at the temperature range 165 – 210°C, whereas it showed an exothermal effect in the temperature range of 300 – 355°C.
- Executive summary:
A study was conducted to determine the thermal stability of the test substance, C12-16 ADBAC (purity: 99.2%) according to the OECD Guideline 113, using differential scanning calorimetry. The crucibles were heated up from 0°C to 360°C with a heating rate of 3 K/min in a nitrogen atmosphere. Under the study conditions, test substance showed two endothermic effects, the first at the temperature range 30 – 45°C and the second at the temperature range 165 – 210°C, whereas it showed an exothermal effect in the temperature range of 300 – 355°C (Moller, 2012).
Reference
The test item BKC showed a first endothermic effect in the temperature range 30 – 45 °C and a second in the temperature range of 165 – 210 °C. The first endothermic effect is related to the melting point, see below. In the temperature range of 300 – 355 °C an exothermal effect could be observed.
Description of key information
The thermal stability was determined using the DSC method according to the OECD Guideline 113 (Moller, 2012)
Additional information
The test substance showed two endothermic effects, the first at the temperature range 30 – 45 ° and the second at the temperature range 165 – 210 °C.
Justification for classification or non-classification
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.
