A gas chromatographic technique has been used to measure the isothermal pha
se equilibria likely to be of importance in petrochemical processing. The m
easurements on the binary mixtures formed by chlorobenzene with some aromat
ic hydrocarbons (toluene, o-xylene, p-xylene) and aliphatic alcohols (ethan
ol, 1-propanol, 1-butanol) are given in this paper. Our measurements on chl
orobenzene + 1-propanol mixtures are in good agreement with the literature
data.
