Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- 169 °C
- Decomp. temp.:
- ca. 280 °C
Any other information on results incl. tables
Using a linear heating rate of about 10 K/min, AGEE 623 Glutaminate started to melt at about 169°C and started to decompose or react at about 280°C in the preliminary test. Due to this results found , the melting point/ melting range was determined by duplicate testing, started at about 167°C.
Two clear stages were observed in this main tests. The melting process started at approximately 168.4°C (Stage B) and ended at 168.9°C (Stage E). During the melting process AGEE 623 Glutaminate changed from a white solid to a yellow-brown liquid. The test substance solidified after cooling down, but the colour remained yellow-brown.
Applicant's summary and conclusion
- Conclusions:
- The melting point of AGEE 623 Glutaminate was determined to be 169°C/ 442 K.
