Preliminary Test
The TGA curve of the test item started at 400 °C, beyond this temperature the weight of the sample decreased significantly. At 476 °C, the sample weight had decreased by 25%.
After the experiment, a brown molten residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item.
Main Study
An endothermic peak in the DSC curve was observed between 100 °C and 150 °C. The extrapolated onset temperature of the peak was 131.225 °C. The endothermic effect was most likely obtained due to melting of the test item. From 275 °C a small exothermic effect was observed. The effect was probably obtained due to reaction and/or decomposition of the test item.
After the experiment, a light yellow molten residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item. Based on this visual observation, it was found that the test item had molten and the change of the colour demonstrated reaction and/or decomposition of the test item.
In order to investigate the melting peak, Experiment 2 was stopped directly after the melting peak. The extrapolated onset temperature was 133.416 °C. After the experiment, a colourless molten residue remained in the sample container. Based on this visual observation, it demonstrated that melting was the reason for the endothermic effect.
The melting temperature was determined as the mean melting temperature of Experiment 1 (131.225 °C) and Experiment 2 (133.416 °C).
Conclusion
The melting and boiling temperature of 4,4'-[isopropylidenebis(4,1-phenyleneoxy)]dianiline were determined by DSC.
The melting temperature of the test item was 132.3 °C (405.5K)
Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of > 275 °C (> 548K). 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.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
