- Boiling pt.:
- 549 K
- Atm. press.:
- 101.325 kPa
Any other information on results incl. tables
Accuracy checking:
The accuracy of the instrument was checked by determining the melting point of a certified sample of benzoic acid ( certified melting point: 123.0°C ±0.3°C).
The results were:
First determination: 123.3°C
Second determination: 123.0 °C
Third determination: 123.2 °C
Boiling point determination:
First determination: 273.5°C
Second determination: 273.6 °C
Correction to normalized pressure:
The atmospheric pressure at the time of the experiment was 97.05 kPa (Meteo Suisse).
A correction of the temperature to normalised pressure (101.325 kPa) was made.
The determination of the correction factor was made using the Sidney Young equation, as recommended in OECD guideline 103.
Applicant's summary and conclusion
- Conclusions:
- From the tests described above, it can be concluded that the standard boiling point of Helvetol is (values rounded off):
549 K (275°C) - Executive summary:
The boiling point of Helvetol was measured according to OECD Guideline No. 103 (principle according to Siwoloboff).
The result can be expressed as follows (values
rounded off):
The boiling point of Helvetol: 549 K (275°C)
