Reference
Preliminary test:
From 200 °C upwards the weight of the sample decreased significantly. At 233 °C the sample weight had decreased by 25%. After the experiment, a yellowish residue remained in the sample container (original colour: colourless). The change of the colour indicated reaction and/or decomposition of the test substance.
Main study:
Experiment 1: An endothermic effect was observed starting at 200 °C. The effect was most likely obtained due to reaction and/or decomposition of the test substance. After the experiment, a colourless residue remained in the sample container. No changes in consistency were observed.
Experiment 2 (performed as a duplicate of experiment 1): A higher end temperature was applied. An endothermic peak between 200 °C and 250 °C was observed. This effect was most likely obtained due to reaction and/or decomposition of the test substance. After the experiment, a yellow/brown deposit remained in the sample container.
Experiment 3 (performed in order to investigate the endothermic effect between 200 °C and 250 °C): A closed sample container was applied. The endothermic peak shifted to lower temperatures between 100 °C and 150 °C. It demonstrated that reaction and/or decomposition of the test substance was the reason for the endothermic effect. After the experiment, a brown deposit remained in the sample container.
Description of key information
No boiling temperature; reaction and/or decomposition of the test substance starting at 100 °C
Key value for chemical safety assessment
Additional information
The boiling behaviour of the substance was investigated using differential scanning calorimetry according to EU Method A.2 and guidelines OECD 103 and OPPTS 830.7220.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
