Vapour-liquid equilibrium in strongly associated systems. The systems acetic acid-propionic acid and acetic acid-trifluoroacetic acid

Vapour-liquid equilibrium was measured in the systems acetic acid-propionic acid and acetic acid-trifluoroacetic acid at normal pressure. Special emphasis has been laid on the correct expression of the P-V-T behaviour in the vapour phase and the analysis of the data obtained.
