Description of key information

Boiling point (hexamethyldisiloxane): 100.5°C at 101.3 kPa

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
100.5 °C

Additional information

A boiling point value of 100.5°C was reported in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered reliable and selected as key study. This value is supported by another boiling point of 99°C in a handbook or collection of reliable data.

In several secondary sources to which reliability cannot be assigned, boiling point values of approximately 90 - 100.5°C were reported for the substance.
