Reference
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.

Description of key information

The boiling point of Reactive Brown 49 by a calculation method based on Meissner et al. is 735 °C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
