During cooling and heating no effects were observed which were due to
crystallization and melting of the test item (results of the cooling
step are archived in the raw data). After the experiment, the sample
appeared to have been unchanged, i.e. no decomposition and/or
evaporation were observed.
To further investigate the melting temperature of the test item, two
subsamples of the test item were stored for 18 hours at -22.5 ± 0.4°C
and at -81.9 ± 2.7°C respectively. It was observed after storage that
the test item was a liquid (≤ -15°C freezer) and a solid (≤-75°C
freezer), respectively. According to this it was concluded that the
melting temperature of the test item is between -75°C and -15°C.
The melting temperature of the tributylphosphine is between -75°C and
