Description of key information

The autoflammability temperature of cyclohexane is 260°C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
260 °C

Additional information

The Merck Index (O'Neil 2006) is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. In addition this is the key reference in the EU RAR (2004) for cyclohexane. The supporting study (WHO ICSC, 1994) is also a peer reviewed source and also reports a value of 260 ˚C (533.15 K) and supports the value reported in the key study.
