- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 350 °C
- Remarks on result:
- not determinable
- Conclusions:
- Decomposition of 4,4'-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) was observed during DSC experiments at temperatures of > 350°C (> 623K). Boiling of the substance was not observed below the temperature at which reaction and/or decomposition started. Based on this, the substance has no boiling temperature.
- Executive summary:
The substance has no boiling temperature.
Reference
From 275°C upwards the weight of the sample decreased significantly. At 344°C the sample weight had decreased by 25%. After the experiment, a colourless residue remained in the sample container (original colour: colourless to light yellow). The change of the colour indicated reaction and/or decomposition of the substance.

Additional information
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.
