Results and discussion

Melting / freezing point
Melting / freezing pt.:
>= 41.3 - <= 68.6 °C

Any other information on results incl. tables

The melting point was determined by Hogg A S (1997) using differential scanning calorimetry, and two distinct peaks were observed in the trace between 41.3 and 68.6°C. It is probable that one peak corresponds to melting of the BDP, while the other corresponds to melting of the impurities.
