Results and discussion
Boiling point
- Key result
- Boiling pt.:
- 149 °C
- Atm. press.:
- 96.95 kPa
Any other information on results incl. tables
Preliminary determination: 142.4 °C
Main test:
First determination: 146.9°C
Second determination: 147.5°C
The atmospheric pressure at the time of the experiment was 96.95 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 GECD guideline 103:
Tn=T+(fr x ~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;
fr = rate of change of boiling temperature with pressure in K/kPa, here a value of 0.35 K/kPa, was used.
T = temperature in K
Tn = normal boiling point
Applicant's summary and conclusion
- Conclusions:
- The boiling point of TBPK was measured according to OECD Guideline N°103 (principle according to Siwoloboff). The result can be expressed as follows:
The boiling point of TBPK: 422 K (149°C) - Executive summary:
The boiling point of TBPK was measured according to OECD Guideline No. 103 (principle according to Siwoloboff). The result can be expressed as follows:
The boiling point of TBPK: 422 K (149°C)
