In this OECD 102 guideline study, the melting point of the test material (EC 239-263-3) was determined to be -8 ºC at 1013.0 hPa. An additional crystal modification can occur with a melting point of 15 ºC at 1013.0 hPa.
Reference
The result presented a mean value of 2 measurements with slow heating rate of 2 K/Min.
Onset temperature: -11°C
An additional crystal modification can occur with a melting temperature of 15 °C.
Quickly cooled down, the test item remained amorphous and showed a glass transition at about -92 °C (Test 1 and Test 2), followed by a recrystallization at about -42 °C peak temperature (all determinations without Test 3).
The melting peak was found at -8 °C peak temperature in the determinations A and B (slow heating rate of 2 K/Min).
Only in Test 1 (1 st heating) another endothermic melting peak was found at +19 °C peak temperature. Together with the small exothermic
peak at -5°C, this must be the melting of another crystal form . Despite several attempts (Test 2-5), this crystal form could not be found in another run and therefore not be studied in detail.
Because the heating rate in this Test 1 was higher than for a precise melting point determination, the found peak temperature (+19.1 °C)
of this special crystal form has to be corrected in the following way:
In the second run of Test 1, 2 and 4 with the same heating rate of 20 K/min, the peak temperature of the melting peak was -4.1 °C
(averaged: -4.6 C, -4.1 °C, -3.5 °C), where the heat flow of this melting was comparable to the high temperature modification. This is a shift by 4.1 K to higher temperatures due to the normal peak shift of the instrument for high heating rates. Vice versa, this peak shift can be assumed to be the same in the 20 K/min run of Test 1 with the high temperature modification.
Therefore, the found peak value of 19.1 °C has to be corrected by th is shift of - 4.1 Kand leads to a corrected peak value of 15.0 °C.
In order to survey the thermic behavior of the test item an additional TG/DTA-Test (non-GLP) was run up to 620 °C.
An exothermic peak starting at about 100 °C with a weight loss of about 100 % at 200 °C showed the vaporization of the test item.
