Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- estimated by calculation
- Adequacy of study:
- key study
- Study period:
- 14 Oct 1998
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- other: Estimation using the Meissner's method (Lyman et al., 1990).
- Principles of method if other than guideline:
- This calculation is based on the relation of the normal boiling points with chemical type; molar refraction (Rd) and parachor (Pa) are used as variables in the correlation.
- Type of method:
- other: estimate by Meissner's method
- Boiling pt.:
- ca. 735 °C
- Atm. press.:
- 101.3 kPa
- Remarks on result:
- other: The boiling point of FAT 40'571/A (as free acid) was calculated to be about 735 °C using Meissner's method.
- Conclusions:
- The boiling point of the FAT 40'571/A was calculated to be about 735 °C.
- Executive summary:
As no melting was observed up to 400 °C, the boiling point of the FAT 40571/A at 101.3 kPa was estimated by a calculation method based on Meissner et al. resulting in an estimate of 735 °C.

Additional information
As no melting was observed up to 400 °C, the boiling point of the Reactive Brown 49 at 101.3 kPa was estimated by a calculation method based on Meissner et al. resulting in an estimate of 735 °C.
