Results and discussion

Melting / freezing point
Melting / freezing pt.:
>= 50 - <= 80 °C
Atm. press.:
ca. 1 013 hPa
Decomposition:
yes
Decomp. temp.:
230 °C

Any other information on results incl. tables

The test item was white powder before heating. Just a part of the item changed transparent at about 50 °C, then the most part of the test item changed transparent between 70 °C to 80 °C.

Decomposition with weight loss is from around 230 °C.

Because the test item is substances of UVCB, a clear peak does not appear and it gradually melts. The peak at 190 °C is the melting point of sucrose (impurities).
