Any other information on results incl. tables
The melting/freezing range is the point at which the test substance changes phase from a solid to
a liquid form. If the test substance is a liquid at room temperature with a freezing point below -
20 °C, the test procedure for freezing point will be effective. Freezing point testing will be
conducted using a test tube and freezing liquid (dry ice/acetone bath). The sample will be gently
stirred to avoid super cooling of the liquid during freezing. The temperature of the liquid will be
monitored and recorded as the sample is cooled. The freezing point will be reported as the
plateau temperature observed in the liquid cooling curve. For substances that do not freeze
above -50 "C, the freezing temperature will be reported as less than -50 °C (223 K).
Applicant's summary and conclusion
- Conclusions:
- The freezing temperature is < -50 °C.
- Executive summary:
The freezing point was conducted using a glass test tube with a Tetlon®-lined screw cap
submerged in an acetone/dry ice bath. An aliquot of test substance was placed in a pre-weighed
test tube and capped. The temperature of the liquid was monitored and recorded as the sample
was cooled.
When the test substance was submerged in a dry ice/acetone bath, no plateau of temperature in
the liquid cooling curve was observed. Thus, the melting/freezing point of the test substance
could not be determined. The freezing temperature is reported as < -50 °C.
