Any other information on results incl. tables

In order to determine the boiling point more precisely, further DSC-runs were recorded between 100 degrees C and 200 degrees C, with a heating rate of 5 K/min. During the main DSC runs, the test item started boiling at 163.1 deg. C and 162.5 deg. C. The sample lost 99.7% and 100% of its mass, respectively. The atmospheric pressure during the measurements was 97.0 kPa.

Applicant's summary and conclusion

Conclusions:
The boiling range of MMP was determined to be 162.8 deg. C to 171.5 deg. C, which is equal to 436.0 K to 444.7 K. The atmospheric pressure during the measurements was 97.0 kPa.
