- Type of method:
- other: thermogravimetric (preliminary test)
- Decomposition:
- yes
- Decomp. temp.:
- >= 240 °C
- Remarks on result:
- not determinable
- Conclusions:
- The boiling point of C14-18 alkyldimethyl ammonium methosulfate could not be determined due to decompositions starting at approx. 240°C.
- Executive summary:
The boiling point of C14-18 alkyldimethyl ammonium methosulfate could not be determined due to decompositions starting at approx. 240°C (preliminary thermogravimetric measurement during determination of melting point; OECD Guideline 102).
Reference
A preliminary thermogravimetric measurement was performed over a temperature range from room temperature to ca. 600 °C.
The mass loss occurred in two steps (58.0 % and 40.0 %) reaching maxima at 301 °C and approximately 401 °C. The total mass loss up to 600 °C was approximately 98 %. There was a small, dark grey residue.
Description of key information
no boiling point detected; decompositions at approx. 240°C
Key value for chemical safety assessment
Additional information
The boiling point of C14-18 alkyldimethyl ammonium methosulfate could not be determined due to decompositions starting at approx. 240°C (preliminary thermogravimetric measurement during determination of melting point; OECD Guideline 102).
