- Conclusions:
- The boiling point of di(tert-butoxy)diacetoxysilane was determined to be 210.2 ± 0.3 ºC at 102.1 kPa.
- Executive summary:
Determination of the boiling point was carried out using the capillary tube in metal block according EU Method A.2 (method according to Siwoloboff) which is in conformity with OECD Guideline 103. The boiling point of di(tert-butoxy)diacetoxysilane was determined to be 210.2 ± 0.3 ºC at 102.1 kPa.
Reference
The values of an initial boiling point of 210.2:
Sample |
Boiling point, ˚C |
1 |
210.5 |
2 |
210.0 |
3 |
210.0 |
Average value ± standard deviation, ºC |
210.2 ± 0.3 |
The average value of an initial boiling point of di(tert-butoxy)diacetoxysilane was determined to be 210.2 ± 0.3 ºC.
The measuring accuracy depends on the BUCHI Melting Point 545 apparatus accuracy (measuring accuracy up to 100.0 ˚C ± 0.3 ˚C; up to 250.0 ˚C ± 0.5 ˚C and up to 400 ˚C ± 0.8 ˚C).
Description of key information
Key study: EU Method A.2. GLP study. The boiling point of di(tert-butoxy)diacetoxysilane was determined to be 210.2 ± 0.3 ºC at 102.1 kPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 210.2 °C
