Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Remarks on result:
other: 1013 hPa assumed

The melting point obtained from the DIPPR 801® Database is recognized by the AIChE as the accepted melting point for trimethoxysilane and is comparable to values from other sources. The AIChE DIPPR 801 Database specifies that the uncertainty associated with the melting point value for trimethoxysilane is < 1%.

Conclusions:
A melting point value of -113.6°C was reported for the substance 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 to be reliable.

Description of key information

Melting point: -113.6°C at 1013 hPa

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-113.6 °C

Additional information

A melting point value of -113.6°C at 1013 hPa was reported for the substance 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 to be reliable and selected as key study.

In other available secondary sources to which reliability could not be assigned, melting point values of -115°C, -114.8°C and -114°C were reported for the substance.
