Reference
Preliminary test:
From 300°C upwards the weight of the sample decreased significantly. At 383°C the sample weight had decreased by 25%. After the experiment, a small dark brown residue remained in the lid of the sample container (original colour: colourless).
Main study:
In the first experiment, during cooling no effects were observed which were due to crystallization of the test substance. Heating showed an endothermic effect above 200°C, which was probably caused by evaporation. The extrapolated onset temperature could not be determined because evaporation continued above 400°C. After the experiment, the consistency appeared to have been unchanged.
During the second and third experiment, a higher end temperature was used in order to determine the extrapolated onset of the boiling temperature. Both DSC-curves showed an endothermic peak between 300°C and 450°C with an extrapolated onset of 385.33°C (second experiment) and 384.56°C (third experiment). After the experiment, a small dark brown residue was observed in the sample container.
Additionally, the test substance was stored overnight in a -20°C freezer in order to determine if crystallization occurs. After storage the test substance had not been crystallized. From this it was concluded that the melting temperature is < -20°C (< 253K).
Description of key information
In a GLP study according to OECD and EU guidelines, the melting/freezing point of diisodecyl adipate was determined to be < -20 degr C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
