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
