- Gaz-phase NMR method:
This is a novel method whihc is based on gas-phase NMR that has been used recently (with proton and fluorine detection) to study the kinetics of a variety of reactions of organic and fluoro-organic compounds in the vapor phase at temperatures up to 400 °C. This method measures the vapor density at various temperatures relative to that of a much more volatile internal mass standard present in much smaller molar amounts of the order of 1 mol %. The vapor density is then converted to vapor pressure using the ideal gas law or another appropriate equation of state. - Type of method:
- dynamic method

- also Gaz saturation method and gaz-phase NMR

Applicant's summary and conclusion
- Conclusions:
- The 8:2 FTOH which is the main constituant of the substance has a vp = 3 Pa at 21°C
- Executive summary:
The vapor pressure of the 8-2 Telomer B alcohol varies from 3 Pa at 21 °C to 101 kPa at 201 °C.
An excellent least-squares fit of the data, including the low temperature measurement by the gas saturation method, was obtained using the Antoine equation, log(P/kPa) = a- b/(c + t/°C) with the parameters a = 6.457, b = 1623, and c = 163.3. Convergence to these values was independent of the starting parameters of the fit. A boiling point of 201.3 °C was extracted (vapor pressure at 101.325 kPa). Excluding the gas saturation value from the data to be fitted has no effect on the resulting Antoine parameters, as expected by the fact that it is several orders of magnitude smaller than the Scott data at substantially higher temperatures. It is reassuring, therefore, keeping in mind the difficulties in extrapolating exponential behavior far from the range of the measurements, that the gas saturation point (3 Pa, 0.023 Torr at 21 °C) falls so close to the extrapolated value based on the Antoine equation (7 Pa at
21 °C).
