Referenceopen allclose all
The lowest temperature at which the application of the ignition source causes the vapor of the test portion to ignite and propagate over the surface of the liquid was defined as the flash point.
Since the flash point of the substance was known from literature (F.P. = 102 °C, Merck catalogue) no pretest had to be performed. The main determination consisted of 2 tests. Starting temperature was T = 80 °C, ignition trials every 1 K temperature rise were carried out.
Flash point (first test): 105 °C
Flash point (second test): 106 °C
Average value: 105.5 °C
The temperature was corrected due to atmospheric pressure.
Flash point of reference substance
In order to check the temperature measurement the flash point of a reference substance with a known value was tested.
Reference substance: 1,2-Propanediole
CAS-Number: 57-55-6
Manufacturer: Merck
Batch Number: K28567978
Flash point: 99°C (Nabert/Schön, Sicherheitstechnische Kennzahlen brennbarer Gase und Dämpfe, Deutscher Eichverlag GmbH, Braunschweig, 2. Auflage, 1991)
The main determination consisted of 3 tests. Starting temperature was T = 80 °C, ignition trials every 1 K temperature rise were carried out.
Flash point (first test): 104 °C
Flash point (second test): 103 °C
Flash point (third test): 103 °C
Average value: 103.3 °C
The temperature was corrected due to atmospheric pressure. As a conclusion the flash point of the reference subsatnce was determined to be at 103.5°C (101.12 kPa)
Description of key information
The flash point of pentanoic anhydride was measured at 104.5 °C at atmospheric pressure of 1013 hPa.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 104.5 °C
Additional information
There is no classification for pentanoic anhydride resulting out of the study on the flashpoint.
