In order to supplement the literature data on VLE, isobaric bubble temperature data were collected for the system phenol-n-propanol over the entire composition range by indirect method using a standard Swietoslawski type ebulliometer. The measurements were made at 200, 400 and 710 mm Hg. The experimentalt—xdata were correlated with both equation of state method and gamma-phi methods. In the former approach the Soave equation of state is used wherfeas in the latter one Wilson, NRTL and UNIQUAC models are used.
