Type of method:

method according to Siwoloboff

Key result

Boiling pt.:

> 145 °C

Atm. press.:

98.9 kPa

Decomposition:

no

Remarks on result:

other: The test substance boiled from about 145 °C on.

At about 145 °C the test substance started boiling and bubbles emerged rapidly from the lower open end of the capillary. Between 145 °C and 180 °C the test substance boiled but on momentary cooling the liquid did not rise in the capillary. At 180 °C the test substance boiled over.

Therefore no boiling temperature of the test substance could be determined. The test substance boiled from about 145 °C on.

Conclusions:

The test substance boiled from about 145 °C on.

Executive summary:

The boiling temperature was determined experimentally using the method according to Siwoloboffof (OECD and EC).

At about 145 °C the test substance started boiling and bubbles emerged rapidly from the lower open end of the capillary. Between 145 °C and 180 °C the test substance boiled but on momentary cooling the liquid did not rise in the capillary. At 180 °C the test substance boiled over. Therefore no boiling temperature could be determined. The test substance boiled from about 145 °C on.

Description of key information

Boiling temperature (OECD 103, EU Method A.2.): The test substance boiled about 145 °C

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

145 °C

Additional information

The boiling temperature was determined experimentally using the method according to Siwoloboffof (OECD and EC).

At about 145 °C the test substance started boiling and bubbles emerged rapidly from the lower open end of the capillary. Between 145 °C and 180 °C the test substance boiled but on momentary cooling the liquid did not rise in the capillary. At 180 °C the test substance boiled over. Therefore no boiling temperature could be determined. The test substance boiled from about 145 °C on.

A supporting study was performed with the main constituent (3-Hydroxy-2-(hydroxymethyl)-2-methylpropionaldehyde) of the test substance. The calculated boiling temperature of the main constituent was determined to be 243.7 °C.
