Results and discussion
Boiling point
- Key result
- Boiling pt.:
- 220 °C
- Atm. press.:
- 97.3 kPa
Any other information on results incl. tables
Preliminary determination: 214°C
Main test:
First determination : 218.3°C
Second determination : 218.3°C
The atmospheric pressure at the time of the experiment was 97.30 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·flp)
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 KlkPa, here a value of 0.40 KlkPa, was used.
T = temperature in K
Tn = normal boiling point
Applicant's summary and conclusion
- Conclusions:
- The boiling point of Isopropyl isopropenyl benzene (MonoPEB) was measured according to GECD Guideline No. 103 (principle according to Siwoloboff). The result can be expressed as follows:
The boiling point of Isopropyl isopropenyl benzene (MonoPEB) : 493 K (220°C) - Executive summary:
The boiling point of Isopropyl isopropenyl benzene (MonoPEB) was measured according to GECD Guideline No. 103 (principle according to Siwoloboff). The result can be expressed as follows:
The boiling point of Isopropyl isopropenyl benzene (MonoPEB) : 493 K (220°C)
