Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
34 °C

Additional information

The boiling points of the primary constituents of GLS-Silane were determined in reliable studies, conducted according to an appropriate test protocol or using an appropriate QSAR method. The boiling points range from 26.7 to 41.5°C at 1013 hPa.

Boiling points:

Dichloromethylsilane : 41.5°C at 1013 hPa

Trichlorosilane: 31.5 - 33°C at 1013 hPa

Chloro(dimethyl)silane: 35.5°C at 1013 hPa

Tetramethylsilane : 26.7°C (no air pressure stated)

The mean value of ca. 34°C at 1013 mbar will be used for the risk assessment.
