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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Boiling point: 150 - 154°C (trichlorotrimethyldisilane)
Boiling point: 153 - 154°C (tetrachlorodimethyldisilane)
Key value for chemical safety assessment
Additional information
No boiling point is available for the substance, Disilane, chloro Me derivs. One reliable measured value is available for the boiling point of 1,1,2,2-tetrachloro-1,2-dimethyl-Disilane (153 - 154 °C) and one reliable measured value for 1,1,2-trichloro-1,2,2-trimethyl-disilane (150 - 154°C); these values are reported in collections of reliable data which have been subject to peer review and in which the original data sources can be traced. Other results given in two other secondary sources, to which reliability could not be assigned, are 158°C and 155°C for 1,1,2,2-tetrachloro-1,2-dimethyl-Disilane and 1,1,2-trichloro-1,2,2-trimethyl-Disilane, respectively. There is no available measured data for 1,2-dichloro-1,1,2,2-tetramethyl-Disilane and a validated QSAR method has not been found for di-silane compounds. Given the similarity in the boiling points of the other two constituents, it can be estimated that 1,2-dichloro-1,1,2,2-tetramethyl-Disilane will be in a similar range.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
