Applicant's summary and conclusion
- Conclusions:
- According to guideline OECD 102 and method EU A.1, no melting point of substance REACTION MASS OF TOLUENE AND 2-VINYL-1,3-DIOXOLANE was observed from - 20°C.
- Executive summary:
A study was performed to determine the melting point/range of test item REACTION MASS OF TOLUENE AND 2-VINYL-1,3-DIOXOLANE.
The method used was Differential Scanning Calorimetry (DSC) and the test was according to Regulation EC No. 440/2008, method A.1 and OECD Test Guideline 102 ''Melting Point/Melting Range''.
In 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.
A cooling system using liquid nitrogen allowed experiments with low temperatures down to -120°C.
Three trials were conducted and corresponding thermograms were obtained, giving us the following results:
Trial Melting point/range Ambient pressure 1 < -20 °C 975.0 hPa 2 < -20 °C 975.0 hPa 3 < -20 °C 975.0 hPa 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 (30.7 J/g for a reference value of 28.6 J/g).
The melting point of the substance was determined as < -20.0°C.
