Description of key information

Dioctanoyl peroxide is a solid at 20 oC with a measured mp of 22-23 oC.

The boiling point of Dioctanoyl peroxide is waived due to decomposition.

The relative density of Dioctanoyl peroxide is 1.0679.

Virtually no particles pass the 100 mm sieve (< 0.03 %). Consequently no PSD was measured.

The vapor pressure of Dioctanoyl peroxide is below 0.1 Pa at 20 oC.

The partition coefficient log Pow value for Dioctanoyl peroxide as determined experimentally is > 6.5.

The water solubility of Dioctanoyl peroxide is 7 ug/L at 20 °C.

Dioctanoyl peroxide is classified as an Organic Peroxide Type C. The substance has no explosive and no oxidising properties.

The Self-Accelerating Decomposition Temperature (SADT) of the substance is 25 °C (reference SADT: CLP regulations 2.15.2.3 and UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 5th revised edition, sub-sections 28.1, 28.2, 28.3 and Table 28.3.).
