EC number: 203-161-7
CAS number: 103-95-7
The accuracy of the instrument was checked by determining
the melting point of a certified sample of benzoic acid (certified
melting point: 122.1 °C ± 0.2 °C). The results were:
First determination: 122.3 °C
Second determination: 122.4 °C
Boiling Point determination
First determination: observed boiling
point: 232.3 °C
Second determination: observed boiling point:
Correction to normalized pressure
The atmospheric pressure at the time of the experiment
was 96.12 kPa (meteo Suisse). A correction of the temperature to
normalised pressure (101.325 kPa) was made. The determination of this
correction factor was made using the Sideney Young equation, as
recommended in OECD guideline 1 03.
Tn = T + (fT.▲p)
Where: ▲p = 101.325 kPa - p
p = pressure in kPa; the pressure
was obtained from the Swiss meteorological service for the time of the
fT = rate of change of
boiling temperature with pressure in K/kPa, here a value of 0.41 K/kPa,
as published in the
OECD guideleine 103, was used.
T = temperature in K
Tn = normal boiling point.
With this correlation made, it can be concluded that the
standard boiling point of Cyclamen Aldehyde Extra is: 507 K (234 °C)
The boiling point of Cyclamen Aldehyde Extra was determined according to OECD guideline No. 103 (principle according to Siwoloboff), using an electronically controlled heating device.
The standard boiling point of Cyclamen Aldehyde Extra was determined to be 507 K (234 °C).
Boiling point 234 °C / 507 K (OECD 103)
The boiling point of Cyclamen Aldehyde
Extra was determined according to OECD guideline No. 103 (principle
according to Siwoloboff), using an electronically controlled heating
The standard boiling point of Cyclamen
Aldehyde Extra was determined to be 507 K (234 °C).
