SEMIMICROMETHOD FOR DETERMINATION OF PARTIAL PRESSURES OF SOLUTIONS

A semimicromethod has been developed for the determination of partial pressures of nonelectrolyte solutions. By suitably constructing the equilibrium still and standardizing the conditions for taking samples of the vapor phase, sufficiently good reproducibility of the results was attained. The function of the instrument was verified by measurements with pure substances: benzene, hexane, and toluene. The x-y-P dependence for the system hexane-toluene at 70° C. was also measured. © 1969, American Chemical Society. All rights reserved.
