ABSTRACT
The high-pressure vapor-liquid equilibria of butane/ethanol system and isobutane/ethanol system were measured by a minimum continuous flow method using a process gas chromatography at 313 403 K. Experimental PXY data were compared with references. The modified RK EOS parameters were regressed and PXY data were also compared with PSRK EOS.
