Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
April, 2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Deviations:
no
GLP compliance:
no
Type of method:
other: thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC)
Key result
Boiling pt.:
>= 139 - <= 242 °C
Decomposition:
yes
Remarks:
Rapid mass loss was observed between 200 and 240 °C.
Decomp. temp.:
>= 139 °C
Remarks on result:
other: The onset of mass loss was at 139 °C (determined from the derivative changing from 0%/°C to 0.1%/°C).

The TGA (thermogravimetry analysis) profile showed the onset of mass loss at 139 °C (determined from the derivative changing from 0%/°C to 0.1%/°C). Rapid mass loss was observed between 200 and 240 °C. The marked endothermic signal in the DSC (differential scanning calorimetry) thermogram revealed that the major mass loss step was related to the volatilization of the sample, possibly after decomposition. There was no evidence of polymerization and oxidation.

             

Conclusions:
Under the test conditions, it was predicted that the test substance had a boiling point greater than or equal to 139°C.
Executive summary:

The boiling point was determined using a DSC and a TGA in the same heating conditions (20 K/min) from ambient temperature to 450 °C. Under the test conditions, the test substance had a boiling point greater than or equal to 139°C.

Description of key information

Boiling point was determined using Differential Scanning Calorimetry (DSC)and Thermo Gravimetry Analysis (TGA)in the same heating conditions from ambient temperature to 450°C (OECD Guideline 103) (Gremmelpretz, 2006). 

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
139 °C
