Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 result
Melting / freezing pt.:
-69.15 °C
Atm. press.:
1 013.25 hPa
Conclusions:
The melting point of tert-Butylperoxy-3,5,5-trimethylhexanoat was determined with -69.15 °C (204.0 K). This value is the mean of two independent determinations.
Executive summary:

The mean between both determinations gives the following value for the melting point:


 


















Melting point



-69.15 °C (204.0 K)



Standard deviation



0.07 (begin of melting process); 0.07 (end of melting process)



Estimated accuracy



± 0.1 °C



 


The melting point of tert-Butylperoxy-3,5,5-trimethylhexanoat was determined with -69.15 °C (204.0 K). This value is the mean of two independent determinations.

Description of key information
