Abstract
Some thermodynamic properties of perfluorotrialkylamines (-ethyl-, -propyl-, and -butyl-) and of perfluoromethyldibutylamine have been investigated. Experimental techniques and methods of estimation of thermodynamic properties are described. The vapour pressures of (CF 3CF 2) 3N, {CF 3(CF 2) 2} 3N, and {CF 3(CF 2) 3} 2NCF 3were determined by an ebulliometric method over the pressure range 6.2 kPa to 101.6 kPa. Enthalpies of vaporization of four amines by a calorimetric method and densities of {CF 3(CF 2) 2} 3N, {CF 3(CF 2) 3} 3NCF 3, and {CF 3(CF 2) 3} 3N have been measured. Critical quantities of the amines under study were calculated by means of the corresponding-states law on the basis of vapour pressures and densities. Thermodynamic quantities for perfluoromethyldibutylamine are preliminary due to a large mole fraction of impurities in the sample studied.
