摘要

Method of determining the vapour-pressure curves and vapour/liquid equilibria of substance mixtures in which the substance mixtures are boiled and in which a) the substance mixture is rectified in a still pot having at least two column sections with a differential pressure of at least 300 mbar and infinite reflux ratio, b) in each case at one or more points in the column sections, product samples of the substance mixture are drawn off in the steady state, preferably with the pressure and/or temperature being measured at the same time, and said product samples are then analysed, for example by gas chromatography, for their percentage composition, c) the lower-boiling components of the substance mixture are partly removed as distillate and the measurements specified under b) are then carried out again. t
