Calibration of the thermometer
The thermometer was checked against a certified thermometer on
February 11, 2021.
A correction did not need to be applied.
Preliminary test
The preliminary test was performed as described. No congealing
was observed down to a temperature of -50.0 °C.
Main test
As no congealing was observed in the preliminary test, no
further tests were undertaken.
Applicant's summary and conclusion
- Conclusions:
- No freezing was observed down to a temperature of -50.0 °C (223.15 K)
Therefore: Freezing point of 2-methyl-3-(p-tolyl)propionaldehyde < -50.0 °c (223.15 K). - Executive summary:
The freezing point of 2-methyl-3-(p-tolyl)propionaldehyde was measured according to the OECD guideline No. 102 ( method of the freezing temperature).
No freezing was observed down to a temperature of -50.0 °C (223.15 K).Therefore: Freezing point of 2-methyl-3-(p-tolyl)propionaldehyde < -50.0 °C (223.15 K).
