The DSC-curve of the preliminary test (heating rate of 20 °C/min from 25
°C to 400 °C) showed a first endothermic heat effect, the melting, at
about 70.8 °C (see Harlan Laboratories study D01028). A second
endothermic heat effect, the boiling, was detected at about 272.8 °C.
After the experiment, the sample had all of its mass and no residue
remained in the sample cup.
In order to determine the boiling point more precisely, further DSC-runs
were recorded between 240 °C and 310 °C with a heating rate of 10
°C/min. During these runs, the boiling point was determined to be 272.1
°C and 272.2 °C. The samples lost less than 4% of their mass,
respectively. After the measurements no residue remained in the sample
The boiling point of CA3610A was determined to be 272.2 °C (Kuehne 2010), which is equal to 545.4 K.The estimated accuracy is ± 0.5 K.This result was obtained using Differential Scanning Calorimetry (Thermal Analysis) method.The atmospheric pressure during the measurements was 99.0 kPa.
A very large body of experimental data exists in the literature for
boiling point. The range of boiling points observed likely reflects
experimental error, as well as the larger effect of different purities.
The boiling point deemed best for classification and risk assessment
purposes is the key study. This is in good agreement with existing
