Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- < 253 K
- Atm. press.:
- 101.32 kPa
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: approx. maximum accuracy of melting point is ± 0.5 deg. K
Any other information on results incl. tables
No thermal events were seen to occur in the thermograms from -20°C to 20°C. Therefore, as confirmation, an aliquot of test material was stored overnight in an approximately -23 °C freezer and was found to not have frozen.
Thermograms: See attached MS word document titled 'Thermograms'.
Applicant's summary and conclusion
- Conclusions:
- The freezing temperature of the test material was determined to be less than 253 ± 0.5 deg. K.
- Executive summary:
A study was conducted to determine the melting point of synthetic inositol phosphates by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, EU Method A1 Melting/Freezing Temperature.
The freezing temperature of the test material was determined to be less than 253 ± 0.5 deg. K.
