EC number: 252-558-1
CAS number: 35435-21-3
Photocell detection method:
The results from the photocell
detection method is shown in Table 1 below.
Table 1: Results – photocell
Measured boiling temperature
Boiling temperature corrected to normal atmospheric pressure
Approximate accuracy of the
instrument: ± 0.3 K (at 373K)
The DSC diagram (blue line) showed
an endothermic peak which represents the boiling temperature. The
simultaneous TG (green line) showed a significant loss of weight in the
range of this peak. The uncorrected boiling temperature (peak onset at
235.8°C) of this measurement corresponds to the values of the capillary
tube/photocell method very closely. The DSC/TG thermograms are attached.
Boiling point: 237.2°C (510.4 K) at 1013 hPa (OECD 103)
A measured boiling point value of
237.2°C (510.4 K) at 1013 hPa was determined for the substance using a
photocell detection method in accordance with OECD 103 Test Guideline
and in compliance with a known quality system (ISO 9001:2008). The
result is considered to be reliable and is selected as key study. The
key study is supported by a boiling point value of 236.1±1°C (509.3±1°K)
at 98 kPa which was determined in a reliable study conducted according
to the OECD test guideline and EU test method. The test was not
conducted at standard atmospheric pressure.
In a secondary source to which
reliability could not be assigned, a boiling point value of 180°C was
reported for the substance.
