ATMOSPHERIC PRESSURE: 101.4 kPa

IGNITION TEMPERATURE AT ATMOSPHERIC PRESSURE: 108 °C / 108 °C

Conclusions:
Flash point of undecan-1-ol: 108 °C at atmospheric pressure.
Executive summary:

Undecan-1-ol was determined according ASTM D93/07. The flash point was determined to be 108 °C at atmospheric pressure.

Description of key information

The closed-cup flash point of undecan-1-ol is 108°C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
108 °C

Additional information

The flash point of 108°C was determined using a rapid equilibrium closed-cup method in accordance with ASTM-D93. The result is considered to be reliable and is selected as key study.

A flash point value of 108°C and boiling point of 247°C indicate that undecan-1-ol should not be classified for flammability in accordance with Regulation (EC) No. 1272/2008.

 

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

The flash point of Category substances follow a predictable trend of increasing flash point temperature with increasing chain length together with increasing boiling point and decreasing vapour pressure.
