- Conclusions:
- The melting temperature of (1,2-Dioxoethylen)bis(iminoethylen)bis[3-(3,5-di-tert-butyl-4- hydroxyphenyl)propionat] was determined at 178°C (451K) by using DSC.
Reaction and/or decomposition of (1,2-Dioxoethylen)bis(iminoethylen)bis[3-(3,5-di-tert-butyl-4- hydroxyphenyl)propionat] was observed during DSC experiments starting at 275°C (548K). Boiling of the test substance was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test substance has no boiling temperature. - Executive summary:
The melting and boiling temperature of the test substance were determined using differential scanning calorimetry (DSC). This technique records the difference in heat flow of two crucibles, one filled with test substance and the other left empty as reference, while these crucibles are subjected to a controlled temperature programme. A transition of the test substance, such as melting or evaporation, is indicated by a deviation from the base line in the heat flow record. Because melting and evaporation are processes in which heat is consumed, the deviation from the base line is in the endothermic direction for these processes. The melting temperature or boiling temperature (if any) of the test substance is evaluated from the DSC curve as the extrapolated onset temperature of the endothermic melting or evaporation peak.
Test was conducted in accordance to:
