EC number: 951-397-0 | CAS number: -
All the raw data (calibration, pre-test and main tests) is in the experimental report.
An endothermic peak assigned to the boiling of the substance was observed and measurement was stopped at 260°C. The initial boiling point of the substance was observed at 185.0°C. Temperature corresponding to this peak was used to create the following temperature program:
Initial temperature (°C)
Final Temperature (°C)
Heating rate (°C/min)
Liquid nitrogen cooling
*Gas injection rate in the furnace.
Mass taken: 10.51 mg
The initial boiling point was observed at 181.5°C (onset temperature of peak) and a corresponding mass loss was observed on the TG curve, showing that all the substance was evaporated at the end of the study.
The crucible was visually checked after the determination: By opening the crucible, no test item left in the crucible and no sign of decomposition was observed.
Atmospheric pressure: 97.5 kPa.
Mass taken: 12.02 mg
The initial boiling point was observed at 181.7°C (onset temperature of the peak) and a corresponding mass loss was observed on the TG curve, showing that all the substance was evaporated at the end of the study.
Atmospheric pressure: 98.2 kPa.
The initial boiling point of the test item was determined to be 181.5°C at 97.5 kPa for the first determination and 181.7°C at 98.2 kPa for the second determination.
In case of small pressure deviations the boiling temperature at standard pressure can be calculated following the equation of Sidney-Young:
Tn= T + (ƒ x ∆p)
Tn= boiling point at 101.325 kPa in K
T = measured boiling point in K
ƒ = correctionfactor (tabulated value)
∆p= (101.325 – p) kPa
P= measured atmospheric pressure in kPa
The corrected values following Sidney-Young equation were determined to be 183.0°C (mean of 183.0°C at 101.3 kPa for the first determination and 182.9°C at 101.3 kPa for the second determination).
Reference substance: Indium
Expected melting point: 156.6 +/- 0.5°C
Obtained melting point: 156.1°C
The melting point of the Indium respects the defined tolerance of the expected melting point.
Expected enthalpy: 28.6 +/- 2.9 J/g
Obtained enthalpy: 28.57 J/g
The enthalpy of the indium respects the defined tolerance of the expected enthalpy.
The study was performed in order to determine the boiling point of test item according to OECD 103, resp. EU A.2, using the DSC method.
Two trials were conducted and corresponding thermograms were obtained (181.5°C at 97.5 kPa and 181.7°C at 98.2 kPa). The initial boiling point values respect validity criteria (less than 0.5°C of difference up to 326.85°C).
Moreover, the melting point of the Indium respects the checking cards limits (156.1°C for a reference value of 156.6°C) so as its enthalpy (28.57 J/g for a reference value of 28.6 J/g). After correction using the Sydney Young equation, the initial boiling point of the substance was determined as 183.0 °C at 101.3 kPa (mean of 183.0 °C for the first determination and 182.9 °C for the second determination).
The initial boiling point of the substance was determined as 183.0 °C at 101.3 kPa (mean of 183.0 °C for the first determination and 182.9 °C for the second determination).
A fully reliable experimental study, conducted according to OECD 102/ EU A1 guideline is available.
It is considered as a key study.
