Results and discussion
Flash point
- Key result
- Flash point:
- 106.5 °C
- Atm. press.:
- ca. 101.3 kPa
Any other information on results incl. tables
The result of the pre-test (anticipated flash point, not to ISO 2719): 106.0°C
The results of the main tests are:
First determination: Flash point, corrected for atmospheric pressure:
107.0°C
Second determination: Flash point, corrected for atmospheric pressure:
106.0°C
As the results of the two determinations were in agreement within
the requirement (the results do not differ by more than 2.0 °C), a third
determination wasn't needed.
The results of the two tests were averaged and rounded off to the
nearest 0.5°C to obtain the final flash point value:
Flash point of 2-methyl-3-(p-tolyl)propionaldehyde: 106.5°C
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Executive summary:
The flash point of 2-methyl-3-(p-tolyl)propionaldehyde was determined by the Pensky-Martens method according to ISO 2719.
The result is: 106.5 °c
