Key result
Melting / freezing pt.:
-32 °C
Atm. press.:
102.6 kPa
Conclusions:
The melting temperature of HEXAHYDRO-1,3,5-TRIMETHYL-S-TRIAZINE was determined using DSC. The melting temperature of the test substance is -32 °C (241 K). The atmospheric pressure was 102.6 +/- 0.1 kPa.
Executive summary:

The melting temperature of HEXAHYDRO-1,3,5-TRIMETHYL-S-TRIAZINE was determined in accordance with EC Method A.1 using DSC. The melting temperature of the test substance is -32 °C (241 K), the atmospheric pressure was 102.6 +/- 0.1 kPa (Baltussen, 2010).
