Key result
Flash point:
ca. 218 °C
Atm. press.:
ca. 101 325 Pa
Conclusions:
The closed cup method was applied for the determination of the flash-point of 4,4'-(4-methylpentane-2,2-diyl)bis((heptyloxy)benzene).
The flash-point of the test item was 218°C.
Executive summary:

The flash-point of the test item was determined using an Eraflash flash-point tester (Eralytics, Vienna, Austria). The Eraflash tester employs a small volume of test item which reduces the risk of fires or other uncontrolled reactions of substances with an unknown flash point. The test cup was filled with approximately 2 ml test item and placed in the holder of the flashpoint tester. The test cup was put in the measurement chamber and the door was closed. The sample was stirred during heating. The ignition of the sample vapour was performed by an electric arc and ignition was automatically detected by the flash point tester. The flash-point is automatically corrected for atmospheric pressure by the flash point tester.

The flash-point of the test item was 218°C.
