Results and discussion

Boiling point
Key result
Atm. press.:
98.8 kPa
Decomposition:
yes
Decomp. temp.:
>= 88 - <= 95 °C

Any other information on results incl. tables

Result : Decomposition.

Comments: Sample started rising in a tube at 88°C. At 95°C gas release was observed and sample ran out of the tube. Due to that the test was terminated. Suspected decomposition.

Applicant's summary and conclusion

Conclusions:
Whereas the test substance decomposes at 88-95°C, the boiling point of the test substance is >88°C.
Executive summary:

Decomposition: 88-95°C. Boiling point: >88°C.
