- Key result
- Atm. press.:
- 101.325 kPa
- Decomposition:
- yes
- Decomp. temp.:
- > 185 °C
- Remarks on result:
- other: Boiling of the test material was not observed. Reaction of decomposition of the test material was observed at temperatures above 185°C.
- Conclusions:
- Boiling of the test substance was not observed. Reaction or decomposition of the test substance was observed at temperature above 185°C (458K).
- Executive summary:
The study was to evaluate the boiling temperature/boiling range of the test substance. Therefore, both test substance sample and reference were heated, using one single heat source. The difference between the heat flow to the sample and the heat flow to the reference were recorded.
Boiling of the test substance was not observed. Reaction or decomposition of the test substance was observed at temperature above 185°C (458K).
Reference
In the first experiment an exothermic effect was observed at temperature above about 185°C (458K) and after the experiment the sample had a black colour. The sample appeared to have lost 2.57 mg (50%) of its mass. The observed exothermic effect was likely to be caused by reaction or decomposition of the test substance.
In the second experiment an exothermic effect started at about 185°C (458K). after the experiment the sample had a dark brown colour. The sample appeared to have lost 0.36 mg (4%) of its mass and the observed exothermic effect was believed to be a reaction or decomposition of the test substance.
Description of key information
The decomposition temperature of SANTICIZER 2148 Plasticizer was determined to be >185°C.
Key value for chemical safety assessment
Additional information
A key OECD Guideline 103 study was conducted to determine the boiling temperature of SANTICIZER 2148 Plasticizer (NOTOX B.V., 1999b).
Using a differential scanning calorimeter (DSC), both test material and reference (sample container filled with alumina) were heated, using one single heat source. The difference between the heat flow to the sample and the heat flow to the reference were recorded.
Boiling of the test material was not observed. Reaction or decomposition of the test material was observed at temperature above 185°C (458K).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
