Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The result was obtained from a handbook which has been subject to peer-review and in which the original data sources are traceable.
Principles of method if other than guideline:
The normal boiling point for tetramethylsilane is based on experimental data (Ashton, J.G., Kennedy, R.M., Messerly, J.F., The Heat Capacity and Entropy, Heats of Fusion and Vaporization and the Vapor Pressure of Silicon Tetramethyl. J. Maer. Chem. Soc., 63, (1941) 2343) that was evaluated and found acceptable by the AIChE DIPPR (1). Original test procedures and conditions used to measure the boiling point were not identified in the AIChE DIPPR Project 801® Database.
GLP compliance:
not specified
Type of method:
other: Not stated
Boiling pt.:
26.6 °C
Atm. press.:
1 013 hPa
Boiling pt.:
299.8 K
Atm. press.:
1 013 hPa

The AIChE DIPPR 801 Database specifies that the uncertainty associated with the normal boiling point value for tetramethylsilane is < 1%.

Conclusions:
A boiling point value of 26.6°C was reported in a handbook or collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
27 °C

Additional information

Boiling point values in the range of 26.5 - 27°C were reported in handbook or collections of reliable data which have been subject to peer review and in which the original data sources are traceable. The results are considered to be reliable and are used as weight of evidence. In available secondary sources to which reliability could not be assigned, boiling point values in the range 26.5 - 26.6°C were reported for the substance. In a disregarded study, boiling point value of 125.5°C was reported for the substance in another secondary source, the result is inconsistent with other available data and as such considered not reliable.
