point was observed at -30.4 °C.
study was performed to determine the melting point/range of test item
(E,Z)-2,6-DIMETHYLOCTA-2,4,6-TRIENE. The method used was Differential
Scanning Calorimetry (DSC) and the test was according to Regulation EC
No. 440/2008 Method A.1 and A.2. and OECD Test Guideline 102 , "Melting
this method, two
crucibles were put in the apparatus furnace under inert atmosphere
(helium) at atmospheric pressure. One crucible contained the test item,
the other was empty and considered as the reference. A specific
temperature program was applied. The crucibles were linked to two
thermocouples fixed on the TG-DSC sample carrier. Heat
flow differences between the two crucibles and mass variation were
recorded on a thermogram.
cooling system using nitrogen allowed experiments with low temperature
down to -150°C.
trials were conducted and corresponding thermograms were obtained,
giving us the following results:
melting point values respect validity criteria (less than 0.5°C of
difference up to 326.85 °C).
the melting point of the Indium
respects the checking cards limits (156.5 °C for a reference value of
156.6 °C) so as its enthalpy (28.8
J/g for a reference value of 28.6 J/g).
No melting point of substance (E,Z)-2,6
-DIMETHYLOCTA-2,4,6 -TRIENE was observed from - 20°C. The melting point
of the substance is -30.1 °C.
melting point of substance (E,Z)-DIMETHYLOCTA-2,4,6-TRIENE is - 30.1°C.
Key study conducted according to the OECD
102 Guideline and the EU A.1 method, under GLP without deviation and
with certificate of analysis included. Therefore, a reliability of 1 is
assigned and the result of this key study is proposed as the end point
