Type of method:
other: Photocell dectection in OECD 103
Specific details on test material used for the study:
Appearance: a colorless colloidal liquid, without irritating odor
Purity: 93% (provided by the sponsor)
Package: in a plastic bottle, packing sound
Amount: 565g
Storage Conditions: sealed and stored at ambient temperature.
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 ℃

Description of key information
