Description of key information

Bis(2-ethylhexyl) peroxydicarbonate does not have a distinct melting point. A melting range of -68.5°C to -66°C was determined.
The melting point for 2-ethyl-1-hexanol, the main degradation product of bis(2-ethylhexyl) peroxydicarbonate is reported to be at -70 °C.
The degradation product is decisive in the environmental risk assessment as the parent substance hydrolyses rapidly (t½ < 1 h at 5 °C).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-70 °C

Additional information

The melting point of bis(2-ethylhexyl) peroxydicarbonate was determined according the OECD guideline 102 resp. EU A.1. The determination was performed in duplicate. In both determinations, a melting range was detected. The melting range was determined as: -68.5 to -66.0 °C (204.8 to 207.2 K). These values are the means of two independent determinations.

The CRC Handbook of Chemistry and Physics cites the melting point for 2-ethyl-1-hexanol, the main degradation product of bis(2-ethylhexyl) peroxydicarbonate to be -70 °C.

The degradation product is decisive in the environmental risk assessment as the parent substance hydrolyses rapidly (t½ < 1 h at 5 °C).
