Purity: 99.78%
Expiry date: 06 June 2019
Storage conditions: Controlled room temperature (15-25°C, <70 RH%), under inert gas, protected from humidity
Key result
Flash point:
111 °C
Atm. press.:
101.3 kPa
Remarks on result:
other: Atmospheric pressure not reported so standard value assumed

Preliminary test was performed from 30 to 200°C. Flash point was observed at 112.2°C. The test item was measured in the main test with two parallel tests from 97°C. The measured flash points of 2 -tert-butyl-1,4 -dimethoxybenzene were 111.3°C and 111.2°C, resulting in a mean value of 111°C.

Interpretation of results:
GHS criteria not met
Conclusions:
The measured flash points of 2-tert-butyl-1,4-dimethoxybenzene were 111.3°C and 111.2°C, resulting in a mean value of 111°C.
Executive summary:

The flash point of Vetimoss was determined using a continuous closed-cup test system, according to EC method A.9. The measured flash points of 2-tert-butyl-1,4-dimethoxybenzene were 111.3°C and 111.2°C, resulting in a mean value of 111°C.
