- 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.
Reference
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
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.
