Key result
Melting / freezing pt.:
-75 °C
Atm. press.:
1 021 hPa

The DSC measurements were performed twice, one run for the lower temperature range on the

power compensation DSC and one for the higher temperature range on the heat flux DSC, using a

crucible with a perforated lid.

The DSC-curve shows an exothermic enthalpy change due to cold crystallization followed byan

endothermic melting peak with peak maximum at -74°C. The extrapolated onset temperature

was determined to -75°C.

Conclusions:
The melting point of Allyl methacrylate is reported to be -75 °C at 1021 hPa (determined according to OECD guideline 102, adopted 27th July 1995, and EU Method A.1, December 1992; differential scanning calorimetry).
Executive summary:

The melting point of Allyl methacrylate is reported to be -75 °C at 1021 hPa (determined according to OECD guideline 102, adopted 27th July 1995, and EU Method A.1, December 1992; differential scanning calorimetry).
