- Atm. press.:

- Decomposition:
- yes
- Decomp. temp.:
- ca. 165 °C
- Remarks on result:
- not determinable
- Remarks:
- No boiling point could be detected prior to decomposition
- Conclusions:
- No boiling point could be detected prior to decomposition.
- Executive summary:
The boiling temperature of N,N'-methylenebis[methacrylamide] was determined by differential scanning calorimetry according to EEC-Directive 92/69 EEC, Part A, Methods for the determination of physico-chemical properties, A.2 "Boiling temperature", EEC Publication No. L383, December 1992. No boiling point could be detected prior to decomposition.
The DSC measurements were performed twice, one run for the lower temperature range on the power compensation DSC Pyris 1 and one for the higher temperature range on the heat flux DSC, using a crucible with a perforated lid.
Interpretation of the differential scanning calorimeter curve: In the first heating cycle the DSC-curve shows an endothermic heat flow with onset at 163 °C due to melting of the sample. The transition to the liquid phase is superimposed by an exothermic process, most probably the decomposition. In the second run from room temperature to 450 °C the same behaviour as in the first run is observable. Due to the decomposition of the sample near 165 °C, no boiling point can be determined at atmospheric pressure.

Applicant's summary and conclusion
- Conclusions:
- Melting Point: 163 °C with decomposition.
- Executive summary:
The melting temperature of N,N'-methylenebis[methacrylamide] was determined by differential scanning calorimetry according to EN ISO 11357-3 (Plastics-Differential Scanning Calorimetry- Part 3 Determination of temperature and enthalpy of melting and crystallization) and EEC-Directive 92/69 EEC, Part A.2 (Methods for the determination of physico-chemical properties, A.1 „Melting temperature“, EEC Publication No. L383, December 1992). The melting point was 163 °C with decomposition.
