RESULTS

Accuracy checking

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: 232.1 °C

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 experiment;

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)

Conclusions:
From this study it can be concluded that the standard boiling point of Cyclamen Aldehyde Extra is 507 K (234 °C).
Executive summary:

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).
