Description of key information
In a Freezing temperature study (TNO report number: PML 2003-C22) the freezing temperature of tetraoctylstannane was determined to be -102 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -102 °C
Additional information
In a Freezing temperature study (TNO report number: PML 2003-C22) the freezing temperature of tetraoctylstannane was determined to be -102 °C.
In experiments 1 and 2, an exothermal effect was observed during cooling. However, the onset of the exothermal peak was not well-defined and no precise onset temperature could be determined. Therefore, it was decided to repeat the tests with a lower heating rate (2 °C/min instead of 10 °C/min). In these experiments, a clear exothermal peak was found and the extrapolated onset temperature could be easily determined. Therefore, the final determination of the onset temperature was based on the results of experiments 3, 4 and 5. All three experiments showed an onset temperature of -102 °C.
In the study protocol, a minimum test temperature of -100 °C was defined. This limit is based on practical use of the freezing temperature determination rather than on experimental or equipment limitations. Therefore, the observed freezing temperature is considered to be a valid result of the study.
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.
