Description of key information

The melting range of di(3,5,5-trimethylhexanoyl) peroxide is outside the detectable range of -70 to 400°C. It may be stated as -75.4 °C or lower.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-75.4 °C

Additional information

The melting point of di(3,5,5-trimethylhexanoyl)peroxide was determined according the OECD guideline 102 (Melting point/melting range) and EU method A.1 (Melting/Freezing Temperature) applying the capillary method. At a temperature of -80 °C the test item was frozen, at -75.4 °C the test item was melted. The test substance does not have a distinct melting point but rather a melting range.

The melting range of di(3,5,5-trimethylhexanoyl)peroxide is outside the detectable range of -70 to 400 °C. It may be stated as -75.4 °C or lower.
