Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:

according to guideline
OECD Guideline 103 (Boiling Point)
GLP compliance:
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
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
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.

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