101.3 kPa

Measurement parameters

Rotation speed of the sample stirrer: 100 rpm

Expected Flash point of the sample: 129.0 °C

Measurement

(repeat determination)

Temperature of initial ignition source application: 110.0 °C / 110 °C

Atmosphreic pressure: 101.7 kPa / 103.0 kPa

Flash point (uncorrrected): 135.0 °C / 135.0 °C

Falsh point (corrected): 135.0 °C / 134.5 °C

Conclusions:
The flash point of Alfol 12- Alcohol was determined to be 134.8 °C at 101.3 kPa.
Executive summary:

The Flash point of dodecan-1 -ol was determined according to ASTM-D93 Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester. Test item was Dodecan-1 -ol, the flash point was measured in duplicate at 2 different days. The value for the corrected flash point was determined to be 135.8 °C.

Description of key information

The flash point of dodecan-1-ol is 134.8°C at 1013 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
134.8 °C

Additional information

The flash point of 134.8°C at 1013 hPa was determined for dodecan-1-ol with the use of non-equilibrium closed-cup method in accordance with ASTM-D93. The result is considered to be reliable.

 

A flash point value of 134.8°C and boiling point of 229°C indicate that dodecan-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.
