Key result

Boiling pt.:

>= 320 °C

Atm. press.:

ca. 1 atm

Decomposition:

yes

Decomp. temp.:

>= 320 °C

samples were heated from room temperature to 320 ℃ under a standard atmospheric pressure and the boiling points of samples were not observed. Then samples turned from colorless colloidal liquid to a black-colored solid;

According to the experimental phenomenon, the boiling point of the sample was not observed until it was heated to 320 ℃. But it had begun to oxidation or decomposition at this temperature. Higher temperatures would accelerate this process, so the boiling point of the sample cannot be detected.

Conclusions:

No boiling point was observed until it was heated to 320 ℃

Additional information

No boiling point was observed until it was heated to 320 ℃
