Experiment 1: during cooling, a glass transition between -40 °C and 0 °C was found (results are archived in the raw data). During heating, a glass transition was observed between -50 °C and 0 °C. The inflection point of the glass transition was -12.949 °C. A small exothermic peak was observed between 150 °C and 250 °C. It was followed by an endothermic effect starting at 300 °C. The effects were most likely due to reaction and/or decomposition of the test item. After the experiment, a yellow residue remained in the sample container.

Experiment 2 was performed to investigate the glass transition temperature. The inflection point of the glass transition was -13.903 °C. After the experiment, a colourless residue remained in the sample container.

The glass transition temperature was determined as the mean glass transition temperature of Experiment 1 (-12.949 °C) and Experiment 2 (-13.903 °C). Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of >150 °C (>423 K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.

Conclusions:

Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of >150 °C (>423 K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.

Executive summary:

The boiling temperature of Epoxypropyl neodecanoate, oligomeric reaction products with cyclohexane-1,2-dicarboxylic anhydride and propylidenetrimethanol was determined by DSC according to OECD 103 & EC A.2. Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of >150 °C (>423 K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
