Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- Due to the nature of the sample, boiling point was determined by thermogravimetric analysis (TGA), which is a
deviation from OECD Guidelines for The Testing of Chemicals, 103, July 27 1995. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: thermogravimetric analysis (TGA)
- Boiling pt.:
- > 128 - < 145 °C
- Atm. press.:
- 101.2 kPa
- Decomposition:
- no
- Remarks on result:
- other:
- Remarks:
- First boiling point
- Boiling pt.:

- Atm. press.:
- 101.2 kPa

- Remarks:
- Second boiling point
- Conclusions:
- Boiling point of 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with 3-aminopropyldiethylamine and 2-piperazin-1-ylethylamine was determined using thermogravimetric analysis (TGA). Material has several components with different boiling point. 5% of the sample shower boiling point in the 128 to 145°C range that is not well-resolved. The lowest major boiling component has a boiling point of 296°C (average) that is not
completely resolved from a higher boiling component. - Executive summary:
Boiling point of 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with 3-aminopropyldiethylamine and 2-piperazin-1-ylethylamine was determined using thermogravimetric analysis (TGA). Material has several components with different boiling point. 5% of the sample shower boiling point in the 128 to 145°C range that is not well-resolved. The lowest major boiling component has a boiling point of 296°C (average) that is not
completely resolved from a higher boiling component.
Reference
TGA results indicate that the sample has several components boiling at different temperatures. The lowest major boiling component has a boiling point of 296°C (average) that is not completely resolved from a higher boiling component. It is possible the sample is decomposing while boiling at the higher temperature boiling point. There is also a minor lower boiling component comprising approximately 5% of the sample with a boiling point in the 128 to 145°C range that is not well-resolved.
