Results and discussion

Melting / freezing point
Melting / freezing pt.:
> 88.3 - < 91.4 °C

Any other information on results incl. tables

4 measurations are provided the following results:

I = 90.4°C

II = 88.3°C

III = 91.4°C

IV = 90.5°C

These values were confirmed by the microscopic of fusion

method.

The observed temperature range was 88 -90 °C.
