Melting Temperature
EC Guideline A.1. Melting/Freezing Temperature. March 04, 2016.
OECD Guideline 102. Melting Point / Melting Range. July 27, 1995.
EPA Product Properties Test Guideline OPPTS 830.7200: Melting Point/Melting Range. March 1998.
The melting temperature of the test item was determined using differential scanning calorimetry (DSC). This technique records the difference in heat flow of two crucibles, one filled with test item and the other left empty or containing an inert reference substance, while these crucibles are subjected to a controlled temperature programme. A transition of the test item, such as melting, is indicated by a deviation from the base line in the heat flow record. Because melting is a process in which heat is consumed, the deviation from the base line is in the endothermic direction for this process.
The melting temperature (if any) of the test item is evaluated from the DSC curve as the extrapolated onset temperature of the endothermic melting effect.
The melting temperature of ISO-MIX were determined by DSC.
No melting point was determined. A glass transition of the test item was observed at -66.2°C (206.9K).
Reference
Preliminary Test
Starting at 150°C, the weight of the sample decreased significantly. At 206°C, the sample weight had decreased by 25%.
After the experiment, a colourless residue with brown/black particles remained in the sample container (original colour: colourless to yellow). The change of the colour indicated reaction and/or decomposition of the test item.
Main Study
During cooling, a glass transition between -90°C and -60°C was found. During heating a glass transition was observed between -75°C and -50°C. The inflection point of the glass transition was -66.267°C. The endothermic and exothermic effect were due to reaction and/or decomposition of the test item.
After the experiment, a yellowish residue with dark spots remained in the sample container (original colour: colourless to yellow). The change of the colour indicated reaction and/or decomposition of the test item.
Experiment 2 was performed to determine the duplicate glass transition temperature. The inflection point of the glass transition was -66.192°C. After the experiment, the sample appeared to have been unchanged, i.e. no decomposition and/or evaporation were observed.
The glass transition temperature was determined as the mean melting temperature of Experiment 1 (-66.267°C) and Experiment 2 (-66.192°C).
Description of key information
No melting point was determined.
Key value for chemical safety assessment
Additional information
The melting temperature of ISO-MIX was determined by DSC.
No melting point was determined. A glass transition of the test item was observed at -66.2°C (206.9K).
